• Nvidia Drivers on Debian / Lenny (Stable) -> Installation successful -> Monitors gets black

  - by David

  I have successfully installed the proprietary drivers for my nvidia (geforce 7300 gt) graphics card on debian/lenny. I know its not the best way to chose for driver installation ( see this link: http://wiki.debian.org/NvidiaGraphicsDrivers#non-freedrivers ). but the two ways seem to be possible for me (nvidia-kernel module compilation). Now the problem is that the monitors gets black, the power light starts blinking after i launch the x-server. Have a short look a the logs (output truncated from /var/log/Xorg.0.log): (II) Setting vga for screen 0.

• Why is my concurrency capacity so low for my web app on a LAMP EC2 instance?

  - by AMF

  I come from a web developer background and have been humming along building my PHP app, using the CakePHP framework. The problem arose when I began the ab (Apache Bench) testing on the Amazon EC2 instance in which the app resides. I'm getting pretty horrendous average page load times, even though I'm running a c1.medium instance (2 cores, 2GB RAM), and I think I'm doing everything right. I would run: ab -n 200 -c 20 http://localhost/heavy-but-view-cached-page.php Here are the results: Concurrency Level: 20 Time taken for tests: 48.197 seconds Complete requests: 200 Failed requests: 0 Write errors: 0 Total transferred: 392111200 bytes HTML transferred: 392047600 bytes Requests per second: 4.15 [#/sec] (mean) Time per request: 4819.723 [ms] (mean) Time per request: 240.986 [ms] (mean, across all concurrent requests) Transfer rate: 7944.88 [Kbytes/sec] received While the ab test is running, I run VMStat, which shows that Swap stays at 0, CPU is constantly at 80-100% (although I'm not sure I can trust this on a VM), RAM utilization ramps up to about 1.6G (leaving 400M free). Load goes up to about 8 and site slows to a crawl. Here's what I think I'm doing right on the code side: In Chrome browser uncached pages typically load in 800-1000ms, and cached pages load in 300-500ms. Not stunning, but not terrible either. Thanks to view caching, there might be at most one DB query per page-load to write session data. So we can rule out a DB bottleneck. I have APC on. I am using Memcached to serve the view cache and other site caches. xhprof code profiler shows that cached pages take up 10MB-40MB in memory and 100ms - 1000ms in wall time. Pages that would be the worst offenders would look something like this in xhprof: Total Incl. Wall Time (microsec): 330,143 microsecs Total Incl. CPU (microsecs): 320,019 microsecs Total Incl. MemUse (bytes): 36,786,192 bytes Total Incl. PeakMemUse (bytes): 46,667,008 bytes Number of Function Calls: 5,195 My Apache config: KeepAlive On MaxKeepAliveRequests 100 KeepAliveTimeout 3 <IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 120 MaxRequestsPerChild 1000 </IfModule> Is there something wrong with the server? Some gotcha with the EC2? Or is it my code? Some obvious setting I should look into? Too many DNS lookups? What am I missing? I really want to get to 1,000 concurrency capacity, but at this rate, it ain't gonna happen.

• Changes made to cli's php.ini not taking effect

  - by Sandeepan Nath

  I have two php.ini files - /etc/php.ini which loads in case of cli /opt/lampp/etc/php.ini which loads in case of browser. I am able to use PHP's Mailparse extension after adding the line extension=mailparse.so in the /opt/lampp/etc/php.ini and restarting lampp. But I am not able to load the same in case of command line - getting PHP Fatal error: Call to undefined function mailparse_msg_create() in ... mailparse_msg_create() is a part of the Mailparse extension. I tried by relogging with the user after making the change and even restarting the system. What needs to be done so that the change takes effect. Update I checked that php -i | grep 'Configuration File' gives PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/mailparse.so' - /usr/lib/php/modules/mailparse.so: cannot open shared object file: No such file or directory in Unknown on line 0 Configuration File (php.ini) Path => /etc Loaded Configuration File => /etc/php.ini Update 2 I copied the mailparse.so from /opt/lampp/lib/php/extensions/no-debug-non-zts-20090626 and put it in /usr/lib/php/modules. I added extension=mailparse.so to /etc/php.ini as well. But it still showed this warning PHP Warning: PHP Startup: Unable to load dynamic library ... As told by Lekensteyn, I did ldd /usr/lib/php/modules/mailparse.so and got ldd: warning: you do not have execution permission for /usr/lib/php/modules/mailparse.so' So I gave execute permission. Then ldd /usr/lib/php/modules/mailparse.so showed linux-gate.so.1 => (0x00110000) libc.so.6 => /lib/libc.so.6 (0x0011d000) /lib/ld-linux.so.2 (0x003aa000) which looks normal. BUt now, running php command says PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/mailparse.so' - /usr/lib/php/modules/mailparse.so: undefined symbol: mbfl_name2no_encoding in Unknown on line 0

• Benchmarking a file server

  - by Joel Coel

  I'm working on building a new file server... a simple Windows Server box with a few terabytes of disk space to share on the LAN. Pain for current hard drive prices aside :( -- I would like to get some benchmarks for this device under load compared to our old server. The old server was installed in 2005 and had 5 136GB 10K disks in RAID 5. The new server has 8 1TB disks in two RAID 10 volumes (plus a hot spare for each volume), but they're only 7.2K rpm, and of course with a much larger cache size. I'd like to get an idea of the performance expectations of the new server relative to the old. Where do I get started? I'd like to know both raw potential under different kinds of load for each server, as well an idea of what our real-world load looks like and how it will translate. Will disk load even matter, or will performance be more driven by the network connection? I could probably fumble through some disk i/o and wait counters in performance monitor, but I don't really know what to look for, which counters to watch, or for how long and when. FWIW, I'm expecting a nice improvement because of the benefits of having two different volumes and the better RAID 10 performance vs RAID 5, in spite of using slower disks... but I'd like to get an idea of how much.

• lighttpd: Backend is overloaded + fcgi-server re-enabled + all handlers are down

  - by AbuZubair

  We have a standard lighttpd deployment with PHP-CGI and our error logs are flooding with the following. This is causing a huge problem because we keep returning 500's to our clients: 2012-10-14 14:28:38: (mod_fastcgi.c.3001) backend is overloaded; we'll disable it for 1 seconds and send the request to another backend instead: reconnects: 0 load: 36 2012-10-14 14:28:38: (mod_fastcgi.c.2764) fcgi-server re-enabled: 0 /tmp/php-7735.socket 2012-10-14 14:28:39: (mod_fastcgi.c.2764) fcgi-server re-enabled: 0 /tmp/php-7735.socket 2012-10-14 14:28:40: (mod_fastcgi.c.3001) backend is overloaded; we'll disable it for 1 seconds and send the request to another backend instead: reconnects: 0 load: 37 2012-10-14 14:28:40: (mod_fastcgi.c.2764) fcgi-server re-enabled: 0 /tmp/php-7735.socket 2012-10-14 14:28:41: (mod_fastcgi.c.3001) backend is overloaded; we'll disable it for 1 seconds and send the request to another backend instead: reconnects: 0 load: 57 2012-10-14 14:28:41: (mod_fastcgi.c.3001) backend is overloaded; we'll disable it for 1 seconds and send the request to another backend instead: reconnects: 0 load: 57 2012-10-14 14:28:42: (mod_fastcgi.c.3597) all handlers for /index.php? on .php are down. Does anyone have any clue as to what is going on? We restarted all php and lighttpd related processes and that didn't fix the problem. We ended up rebooting the whole box and now its gone away, although we fear it may come back later.... In general our deployment has been doing fine for a long time and this is the first time this has happened.

• OpenAM throwing 302 0 behind haproxy, nginx

  - by Travis

  I'm having some issues with my deployment and was wondering if you can help. My set up is as follows: 2 OpenAM servers are set up behind a load balancer (HAproxy). The load balancer is set up behind two reverse proxies (nginx). The two reverse proxies are ser up behind another load balancer (haproxy). So a request will go through Haproxy nginx Haproxy openam I can access the OpenAM web console through the reverse proxies without a problem. Everything works fine at this level. However when I access openam through the load balancer in front of the reverse proxies Openam throws a 302 error. The funny thing is however I can access the host/openam/UI/Login and login successfully. I even get the cookie and have access to my apps that are set up. However immediately after the login OpenAM throws a 302 redirect. I'm puzzled and cannot figure out what is going wrong. Does anyone have any idea? My config files are below: nginx config : server { listen 443; server_name oamlb1; location / { proxy_pass http://oamlb1.mydomain.com:8080; proxy_set_header X-Real-IP $remote_addr; } location /openam { proxy_pass http://oamlb1.mydomain.com:8080; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host oamlb1.mydomain.com:8080; } } haproxy config : (This file is for the servers. The file for the reverse proxies is idenical except it points to the reverse proxies) listen http_proxy :8090 mode http balance roundrobin option httpclose option forwardfor server webA oamserver1.mydomain.com:18080 option forwardfor Thanks

• SAN with iSCSI-Target Performance Horrendous

  - by Justin

  We have a poor man's SAN setup in a 1U Ubuntu server running iSCSI-Target with two 300GB drives in RAID-0. We then are using it for block level storage for virtual machines. The hypervisor is connected to the SAN via gigabit on a dedicated VLAN and interfaces. We only have a single virtual machine setup and doing some benchmarks. If we run hdparm -t /dev/sda1 from the virtual machine, we get 'ok' performance of 75MB/s from the virtual machine to the SAN. Then we basically compile a package with ./configure and make. Things start ok, but then all the sudden the load average on the SAN grows to 7+ and things slow down to a crawl. When we SSH into the SAN and run top, sure the load is 7+, but the CPU usage is basically nothing, also the server has 1.5GB of memory available. When we kill the compile on the virtual machine, slowly the LOAD on the SAN goes back to sub 1 figures. What in the world is causing this? How can we diagnosis this further? Here are two screenshot from the SAN during high load. 1> Output of iotop on the SAN: 2> Output of top on the SAN:

• Running a powershell script at startup

  - by RandellK02

  I am writing a script to remove a computer from the domain, rename it, then add it back. It works fine when I set the trigger to AtLogOn but when I switch to AtStartUp I run into some issues. I get this error when it restarts to run the first scheduled task: 0x8007051F: There are currently no logon servers available to service the logon request. I suspect the script tries to run with no network connection set up so I tested using the RandomDelay parameter, and it worked like its suppose to. I cant rely on a random delay so I am looking for an alternative. Is there a way to test the network status before the script begins or a way to delay the script a specific amount of time? I am using Register-ScheduledJob provided by Powershell 3.0 Thanks in advance

• Apache mod-pagespeed installation affects mod-spdy?

  - by tim peterson

  Recently my site (an https connection, running on an Amazon EC2 ubuntu apache2.2) has this issue where I need to load the page several times (3-4) before it will load normally without issue. It will then load normally as long as I keep loading pages regularly (every couple seconds). It will stall again if I don't load pages for a few minutes. It has nothing to do with my application because I don't have this problem with the exact same app codebase on my Apache installation on my laptop. The only things to my knowledge that I've changed is that I recently installed mod_spdy and then a few weeks later I installed mod_pagespeed, https://developers.google.com/speed/pagespeed/mod. However, I have since turned mod_pagespeed off by setting its pagespeed.conf to mod_pagespeed off. Unfortunately, that didn't solve the problem. The line below is how every of last 10 lines of my error.log look: # tail -f /var/log/apache2/error.log ... [32728:32729:ERROR:mod_spdy.cc(162)] request->chunked == 1 in request GET / HTTP/1.1 [Sat Jun 02 04:50:08 2012] [warn] [client 50.136.93.153] [stream 5] [32728:32729:WARNING:http_to_spdy_filter.cc(113)] HttpToSpdyFilter is not the last filter in the chain: chunk any thoughts? thank you, tim

• Page reload needed several times before loading normally

  - by tim peterson

  Sorry my question is so vague I just have no idea where to start in solving it and am quite a novice with servers. Recently my site (an https connection, running on an Amazon EC2 ubuntu apache2.2) has this issue where I need to load the page several times (3-4) before it will load normally without issue. It will then load normally as long as I keep loading pages regularly (every couple seconds). It will stall again if I don't load pages for a few minutes. It has nothing to do with my application because I don't have this problem with the exact same app codebase on my Apache installation on my laptop. The only thing to my knowledge that I changed is that I installed mod_pagespeed https://developers.google.com/speed/pagespeed/mod. However, I have since turned it off by setting my pagespeed.conf to mod_pagespeed off. Unfortunately, that didn't solve the problem. I'm wondering general advice on how to troubleshoot this problem. For instance are there linux commands to check page loading peformance? Also, it looks like I have lots of new error.logs in my /var/log/apache2 directory which i believe weren't there a few months ago. lots of this : error.log RewriteLog.log.24.gz ssl_access.log.40.gz error.log.1 RewriteLog.log.25.gz ssl_access.log.41.gz error.log.10.gz RewriteLog.log.26.gz ssl_access.log.42.gz error.log.11.gz RewriteLog.log.27.gz any thoughts? thank you, tim

• Parsing the output of "uptime" with bash

  - by Keek

  I would like to save the output of the uptime command into a csv file in a Bash script. Since the uptime command has different output formats based on the time since the last reboot I came up with a pretty heavy solution based on case, but there is surely a more elegant way of doing this. uptime output: 8:58AM up 15:12, 1 user, load averages: 0.01, 0.02, 0.00 desired result: 15:12,1 user,0.00 0.02 0.00, current code: case "`uptime | wc -w | awk '{print $1}'`" in #Count the number of words in the uptime output 10) #e.g.: 8:16PM up 2:30, 1 user, load averages: 0.09, 0.05, 0.02 echo -n `uptime | awk '{ print $3 }' | awk '{gsub ( ",","" ) ; print $0 }'`","`uptime | awk '{ print $4,$5 }' | awk '{gsub ( ",","" ) ; print $0 }'`","`uptime | awk '{ print $8,$9,$10 }' | awk '{gsub ( ",","" ) ; print $0 }'`"," ;; 12) #e.g.: 1:41pm up 105 days, 21:46, 2 users, load average: 0.28, 0.28, 0.27 echo -n `uptime | awk '{ print $3,$4,$5 }' | awk '{gsub ( ",","" ) ; print $0 }'`","`uptime | awk '{ print $6,$7 }' | awk '{gsub ( ",","" ) ; print $0 }'`","`uptime | awk '{ print $10,$11,$12 }' | awk '{gsub ( ",","" ) ; print $0 }'`"," ;; 13) #e.g.: 12:55pm up 105 days, 21 hrs, 2 users, load average: 0.26, 0.26, 0.26 echo -n `uptime | awk '{ print $3,$4,$5,$6 }' | awk '{gsub ( ",","" ) ; print $0 }'`","`uptime | awk '{ print $7,$8 }' | awk '{gsub ( ",","" ) ; print $0 }'`","`uptime | awk '{ print $11,$12,$13 }' | awk '{gsub ( ",","" ) ; print $0 }'`"," ;; esac

• Unable to install PEM/pkcs12 created by gnutls to Cisco ASA

  - by ACiD GRiM

  I've been pulling some hair out trying to figure out why cisco devices don't like my certificates. My primary need is to get a trustpoint set up with CA,cert,key on the ASA for VPN systems, however I'm having the same issues on my IOS devices. I created a pkcs12 with openssl a few months ago that imported with no issues, but now that I'm getting ready to move this lab to production I'm using gnutls certtool as I found it adds alt_dns and ip_address fields properly to the certificate, (which cost me a few more hairs trying to get to work with openssl's ca tool) I'm including the current test certs below, don't worry I'm not using these in production ;) The maddening thing is that after I thought gnutls was generating certs incorrectly, I tried making a pkcs12 for a printserver and it imported with no issues. Here's my command flow for creating these certs: certtool --generate-privkey --disable-quick-random --outfile nn-ca.key certtool --generate-self-signed --load-privkey nn-ca.key --outfile nn-ca.crt certtool --generate-privkey --disable-quick-random --outfile nn-g0.key certtool --generate-certificate --load-privkey nn-g0.key --outfile nn-g0.crt --load-ca-privkey nn-ca.key --load-ca-certificate nn-ca.crt openssl pkcs12 -export -certfile nn-ca.crt -in nn-g0.crt -inkey nn-g0.key -out nn-g0.p12 openssl enc -base64 -in nn-g0.p12 -out nn-g0.base64.p12 The password for the attatched pkcs12 is "ciscohelp" without quotes. Thanks for any help TestCerts

• Powershell: Execute exe on remote server and capture output

  - by user364825

  I am trying to script the execution of an installer on remote web servers. The installer in question is also a Windows Service that hosts NServiceBus. If RDP'd into the server, the application is installed by the following command: &"$theInstaller" /install /serviceName:TheServiceName The installer prints output about its progress registering the service and connecting to the database to stdout, among other things. This works fine from an RDP session, but when I execute it remotely via PS, I get a you-can't-do-this-over-the-network message if I execute it directly or via Invoke-Command -computername $theRemoteServer: System.IO.FileLoadException: Could not load file or assembly 'file://\\theRemoteServer\c$ \thePath\AutoMapper.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515) --- System.NotSupportedException: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information. (Note: I added an additional "\" to the path in the first line in order to get it to show up correctly in the preview on this site.) This, and other DLLs, are loaded by the service, and the service's execution context cannot, apparently, be remotified. I have also tried using Invoke-WmiMethod, which does something, but it's not clear what, and the output from the installer is lost: Invoke-WMIMethod win32_process create '"$theInstaller" /install /serviceName:TheServiceName' -ComputerName $server (with and without cmd.exe /k before the intaller reference): __GENUS : 2 __CLASS : __PARAMETERS __SUPERCLASS : __DYNASTY : __PARAMETERS __RELPATH : __PROPERTY_COUNT : 2 __DERIVATION : {} __SERVER : __NAMESPACE : __PATH : ProcessId : ReturnValue : 9 How does one remotely execute such an EXE and capture the output?

• Latency in Sending and Receiving Files From Amazon EC2 - Justification

  - by Adroidist

  I am facing a huge delay while uploading and downloading files from my Windows Amazon EC2 server to my android device. It takes around 50 seconds to upload then download 500 Kbytes image. My location is in asia and the server is is US-East. I pinged the server from my android and obtained values around 500 ms for RTT. Is this normal? How is this explained? I tried this website: http://cloudharmony.com/speedtest/run and obtained that downloading 270 Kbytes file takes around 20 seconds. How is this delay justified?

• APC Smart UPS network shutdown issue

  - by Rob Clarke

  Here is a bit about our setup: We have 2x Smart-UPS RT 6000 XL units with network management cards We are running Powerchute from a network server Powerchute is connected to the management cards of both UPSs UPSs are set to do a graceful shutdown via Powerchute when the battery duration is under 20 minutes We also have a command file that runs with Powerchute Although our setup is redundant we do not have an equal load on each server due to APC switches for single power devices The problem is that as we do not have an equal load on each server the batteries drain at different rates. This means that the UPSs both get to the specified low battery duration at completely different times. The problem here is that UPS 1 may have run down to 5 minutes and is in desperate need of initiating a Powerchute shutdown - UPS 2 still has 25 minutes of runtime so no shutdown is initiated. Consequently UPS 1 goes down and takes all the servers with and then shuts down UPS 2 as well! What we need to happen are 1 of either 2 things: Powerchute initiates the shutdown as soon as either UPS reaches the 20 minutes low battery duration setting - and doesnt wait for both The UPS with the heavier load expends its entire battery but does not shutdown both UPSs and lets the load be switched across to the UPS that still has runtime remaining. That way when the UPS that still has runtime reaches its low battery duration it can proceed with the graceful shutdown via Powerchute. Hope that makes sense, any help is greatly appreciated!

• RabbitMQ message consumers stop consuming messages

  - by Bruno Thomas

  Hi server fault, Our team is in a spike sprint to choose between ActiveMQ or RabbitMQ. We made 2 little producer/consumer spikes sending an object message with an array of 16 strings, a timestamp, and 2 integers. The spikes are ok on our devs machines (messages are well consumed). Then came the benchs. We first noticed that somtimes, on our machines, when we were sending a lot of messages the consumer was sometimes hanging. It was there, but the messsages were accumulating in the queue. When we went on the bench plateform : cluster of 2 rabbitmq machines 4 cores/3.2Ghz, 4Gb RAM, load balanced by a VIP one to 6 consumers running on the rabbitmq machines, saving the messages in a mysql DB (same type of machine for the DB) 12 producers running on 12 AS machines (tomcat), attacked with jmeter running on another machine. The load is about 600 to 700 http request per second, on the servlets that produces the same load of RabbitMQ messages. We noticed that sometimes, consumers hang (well, they are not blocked, but they dont consume messages anymore). We can see that because each consumer save around 100 msg/sec in database, so when one is stopping consumming, the overall messages saved per seconds in DB fall down with the same ratio (if let say 3 consumers stop, we fall around 600 msg/sec to 300 msg/sec). During that time, the producers are ok, and still produce at the jmeter rate (around 600 msg/sec). The messages are in the queues and taken by the consumers still "alive". We load all the servlets with the producers first, then launch all the consumers one by one, checking if the connexions are ok, then run jmeter. We are sending messages to one direct exchange. All consumers are listening to one persistent queue bounded to the exchange. That point is major for our choice. Have you seen this with rabbitmq, do you have an idea of what is going on ? Thank you for your answers.

• Why do password entries over ssh take so long?

  - by Dean

  When I'm ssh'd into my server, any time I enter my password, there's a 40 second delay before the server responds. This occurs when logging in, as well as whenever I run a command via sudo. The delay does not happen when I run su and enter my password however. Using the -v flag for ssh doesn't show anything during this time. Looking at Wireshark, all traffic between the two machines stops while this is happening. Any idea what's happening, or advice on how to investigate this? The server is running Debian squeeze (6.0.4)

  I've got a similar problem to "BSOD - Unable to verify timestamp for ntoskrnl.exe", in that I can't seem to get the correct symbols to read ntoskrnl.

• Windows 7 Loading speed

  - by Sergiy Byelozyorov

  I have installed Windows 7 64-bit about two week ago. Since then everything was working alright, but yesterday Windows started to load much slower. Main delay comes while Windows logo is glowing -- it used to be around 10-15 seconds and now it's around 2 minutes. As far as I remember, I have only installed Microsoft IntelliMouse driver recently and removed it today. Unfortunately I found out that I have switched off System Restore some time long ago, so can't even test if the problem can be fixed by restoring old version. How can I troubleshoot the problem? Can I somehow find out what's causing the delay? P.S. Please don't suggest to reinstall Windows. I know that will help, but reinstalling all software and settings is a pain and requires a lot of time.

• Very uneven CPU utilization with SQL Server 2012 on 2 processor computer with 16 cores / processor

  - by cooplarsh

  After installing SQL Server Enterprise 2012 with the Server + Cal license model, on a computer with 2 processors each with 16 cores (and no hyperthreading involved) and putting the server under extremely heavy load the 16 cores on the first processor were very underutilized, the first 4 cores on the 2nd CPU were heavily utilized, and the last 12 cores were not used at all (because of the 20 core limit for this sql server version). Total CPU utilization was displaying as around 25%. Unfortunately, the server suffered from extremely poor performance even though if the tasks were evenly distributed across the 20 cores it wouldn't have been anywhere near as bad. The Windows Server was running on a VMWare virtual image under ESX Server, but all of the CPU was allocated to the windows server. We tried changing affinity settings (e.g., allocating most cores to CPU and the others to I/O), but that didn't help solve the performance problems. Upgrading the product edition to SQL Server Enterprise Core 2012 not only allowed the SQL Server to utilize the 12 previously unused cores on the 2nd processor, but it also resulted in a much more even distribution of tasks across all of the processors. To get through the backlog of requests cpU utilization jumped to around 90%, and then came down to around 33% once it was caught up, but performance improved dramatically since we failed over to the newly updated version And the performance issues went away. I was wondering if anyone knows what might cause SQL Server to unevenly distribute the load, relying almost exclusively on the first 4 cores of the 2nd processor that had 12 cores idle, and allocate only a few tasks to each of the 16 cores on the first processor. Also, is there any way we could have more evenly distributed the load across the 20 cores that were being used without the product edition upgrade? The flip side of that question is what did the product upgrade do that caused SQL Server to start evenly distributing the load across all of the cores that it recognized? Thanks to any insight to answer these questions and/or links that might help me better understand how to make sense of what was happenings.

• APC Smart UPS network shutdown issue

  - by Rob Clarke

  Here is a bit about our setup: We have 2x Smart-UPS RT 6000 XL units with network management cards We are running Powerchute from a network server Powerchute is connected to the management cards of both UPSs UPSs are set to do a graceful shutdown via Powerchute when the battery duration is under 20 minutes We also have a command file that runs with Powerchute Although our setup is redundant we do not have an equal load on each server due to APC switches for single power devices The problem is that as we do not have an equal load on each server the batteries drain at different rates. This means that the UPSs both get to the specified low battery duration at completely different times. The problem here is that UPS 1 may have run down to 5 minutes and is in desperate need of initiating a Powerchute shutdown - UPS 2 still has 25 minutes of runtime so no shutdown is initiated. Consequently UPS 1 goes down and takes all the servers with and then shuts down UPS 2 as well! What we need to happen are 1 of either 2 things: Powerchute initiates the shutdown as soon as either UPS reaches the 20 minutes low battery duration setting - and doesnt wait for both The UPS with the heavier load expends its entire battery but does not shutdown both UPSs and lets the load be switched across to the UPS that still has runtime remaining. That way when the UPS that still has runtime reaches its low battery duration it can proceed with the graceful shutdown via Powerchute. Hope that makes sense, any help is greatly appreciated!

• Postfix qmgr process causes heavy overload on mailservers

  - by Mattias

  We are using Postfix as MTA for our e-mailmarketing software and once in a while we see that the load on one of the mailservers rises above 5. The load is caused by the qmgr-process which is the heart of Postfix and I see that it is consuming a lot of CPU resources. The process seems to be stuck because after 15 minutes it is still doing the samething and still increasing the load. Once I restart the postfix service the load rapidly decreases to below 1 and Postfix continues to send e-mails without any problems. I'm wondering if anyone else has encountered this problem and if people have suggestions on how to prevent it. The problem shows up on all our mailservers but almost never at more than 1 at the time. It seems to be triggered only when we are sending a mailing but the size (10 or 100.000 e-mails doesn't seem to make a difference). It maybe happens once a week or even less often and the time and day is also different every time. We tried to solve the problem by decreasing the amount of messages qmgr is allowed to process but this didn't solve it. We are using Postfix 2.5.5 on Debian Lenny 5.0.8 (postfix is installed through the default Debian repository). No special messages can be found in the logs (syslog, messages, mail.*). Thank you for your time

• Mapping Super+hjkl to arrow keys under X

  - by Bill Casarin

  I'm trying to map: Super+h -> Left Super+j -> Down Super+k -> Up Super+l -> Right globally under X. The idea is I don't want to leave my home row that often to use the arrow keys, so I'll use the Super modifier + hjkl to emulate the arrow keys under X. Is there any way to do this? One thing I've tried is xbindkeys + xte using this configuration: "xte 'keydown Up' 'keyup Up'" Mod4+k "xte 'keydown Down' 'keyup Down'" Mod4+j "xte 'keydown Left' 'keyup Left'" Mod4+h "xte 'keydown Right' 'keyup Right'" Mod4+l but there seems to a large delay between me pressing the key and noticing any result, and most of the time nothing happens at all. Is there a more elegant way of doing this that actually works with no delay?

• What file transfer protocols can be used for PXE booting besides TFTP?

  - by Stefan Lasiewski

  According to ISC's dhcpd manpage: The filename statement filename "filename"; The filename statement can be used to specify the name of the initial boot file which is to be loaded by a client. The filename should be a filename recognizable to whatever file transfer protocol the client can be expected to use to load the file. My questions are: What file transfer protocols, besides tftp, are available to load the file (e.g. What protocols "can be expected to" load the file)? How can I tell? Can I see a list of these protocols? Does my choice of DHCP server influence which file transfer protocols are in use? Pretend I want to use dnsmasq instead of ISC's dhcpd Are these features dependent on the PXE which is in use (e.g. My Intel NICs use an Intel ROM)? I know that some PXE-variants, such as iPXE/gPXE/Etherboot, can also load files over HTTP. However, the PXE rom needs to be replaced with the iPXE image, either by chainloading or by burning the PXE rom onto the NIC. For example, the iPXE Howto "Using ISC dhcpd" says: ISC dhcpd is configured using the file /etc/dhcpd.conf. You can instruct iPXE to boot using the filename directive: filename "pxelinux.0"; or filename "http://boot.ipxe.org/demo/boot.php";
