  • Any reason not to disable Windows kernel paging?

    - by Nathaniel
    So I'm planning on eventually going to 2 GB (mobo max) RAM from 1 GB, and I want to disable kernel paging once I do, because I've heard it can give a performance boost (and that I believe). Any reason not to do it or any general thoughts about it? Edit: for clarification, this is not disabling general RAM paging. This is disabling having kernel memory paged (or at least parts of it, as Charlls noted).

  • Coldfusion autorestart

    - by Comcar
    Coldfusion is automatically restarting, a lot. It comes in waves, everything seems fine for a while then the server struggles for a few minutes, restarts a lot then settles down again. I have Fusion Reactor installed, but when CF goes down FR stops logging so it's not really helping. Looking through the archived logs just shows gaps in the logs. These are all the occourances of the phrase "Coldfusion started" today. [root@server2 logs]# grep -i "Coldfusion started" server.log | grep "11/27/12" "Information","main","11/27/12","01:49:35",,"ColdFusion started" "Information","main","11/27/12","01:50:46",,"ColdFusion started" "Information","main","11/27/12","01:52:39",,"ColdFusion started" "Information","main","11/27/12","01:54:08",,"ColdFusion started" "Information","main","11/27/12","01:55:12",,"ColdFusion started" "Information","main","11/27/12","01:56:29",,"ColdFusion started" "Information","main","11/27/12","01:57:36",,"ColdFusion started" "Information","main","11/27/12","01:58:57",,"ColdFusion started" "Information","main","11/27/12","01:59:56",,"ColdFusion started" "Information","main","11/27/12","02:01:38",,"ColdFusion started" "Information","main","11/27/12","02:03:11",,"ColdFusion started" "Information","main","11/27/12","02:04:41",,"ColdFusion started" "Information","main","11/27/12","02:07:53",,"ColdFusion started" "Information","main","11/27/12","02:10:45",,"ColdFusion started" "Information","main","11/27/12","02:11:49",,"ColdFusion started" "Information","main","11/27/12","02:13:09",,"ColdFusion started" "Information","main","11/27/12","02:14:18",,"ColdFusion started" "Information","main","11/27/12","02:15:44",,"ColdFusion started" "Information","main","11/27/12","02:17:06",,"ColdFusion started" "Information","main","11/27/12","02:34:19",,"ColdFusion started" "Information","main","11/27/12","03:01:20",,"ColdFusion started" "Information","main","11/27/12","05:25:59",,"ColdFusion started" "Information","main","11/27/12","06:30:48",,"ColdFusion started" "Information","main","11/27/12","06:36:20",,"ColdFusion started" "Information","main","11/27/12","09:34:07",,"ColdFusion started" "Information","main","11/27/12","09:35:39",,"ColdFusion started" "Information","main","11/27/12","09:36:41",,"ColdFusion started" "Information","main","11/27/12","09:39:15",,"ColdFusion started" "Information","main","11/27/12","09:40:42",,"ColdFusion started" "Information","main","11/27/12","09:42:55",,"ColdFusion started" "Information","main","11/27/12","09:44:23",,"ColdFusion started" "Information","main","11/27/12","09:46:18",,"ColdFusion started" "Information","main","11/27/12","09:47:35",,"ColdFusion started" "Information","main","11/27/12","09:48:53",,"ColdFusion started" "Information","main","11/27/12","09:50:04",,"ColdFusion started" "Information","main","11/27/12","09:51:51",,"ColdFusion started" "Information","main","11/27/12","09:53:05",,"ColdFusion started" "Information","main","11/27/12","09:54:24",,"ColdFusion started" "Information","main","11/27/12","09:55:28",,"ColdFusion started" "Information","main","11/27/12","09:56:38",,"ColdFusion started" "Information","main","11/27/12","09:58:03",,"ColdFusion started" "Information","main","11/27/12","09:59:03",,"ColdFusion started" "Information","main","11/27/12","10:04:37",,"ColdFusion started" "Information","main","11/27/12","12:04:02",,"ColdFusion started" I've been looking at the live server metrics in FR on a second screen all day, the CPU, Memory and requests all seemed fine about 12 midday, then the server rebooted. Looking at the logs for the hour between 9am and 10am (more than 15 restarts in the hour), the CPU never went over 44% usage and the Memory never exceeded 53% usage - in the recorded stats at least. There is no JDBC tracking at the moment, so I'll add that to tracking and see if it's MySQL causing a problem, but can anyone help me narrow down the problem, what would cause Cold Fusion to auto restart, and I'm assuming the auto restart is only happening because Fusion Reactor is installed. It's a Red Hat 5 LAMP stack running Coldfusion 9 and Fusion Reactor 4.5.2

  • Apache jamming at low load average

    - by Apikot
    Apache seems to stop responding sometimes even though apache processes are still running. After restarting apache, the load average usually shoots up from 1 - 2 to 13 - 15 in a matter of seconds. What would the cause of this be, or how could I find out why apache stops serving? My httpd.conf is: <IfModule mpm_prefork_module> StartServers 8 MinSpareServers 5 MaxSpareServers 20 MaxClients 50 ServerLimit 50 MaxRequestsPerChild 4000 </IfModule> It's running on an EC2 c1.medium (1.7 GB of memory) Thanks

  • Is there a way to tell SGE to run specific jobs as root on the execution node?

    - by Rick Reynolds
    The title kinda says it all... We're using SGE/OGE to submit jobs to a set of worker nodes that then do things with specific pieces of equipment. The programs and scripts that have been created that manipulate this equipment rely on running as root. I'd like SGE to handle allocation of resources in a way that is mindful of users, groups, projects, etc., but I also need the actual jobs to run with root permissions. I've read up on How can one run a prologue script as root in gridengine? to see if anything there was pertinent, but it seems that SGE is providing the "user@" kind of spec specifically for prolog and epilog kinds of actions. Is there any similar functionality for the job itself? I'm aware of su/sudo approaches, but that won't really work in this environment because the sudoers file isn't globally managed (i.e. I'd have to add a whole set of users to /etc/sudoers on lots of machines). I'm currently looking into a setuid kind of solution, but that would definitely be an unnecessary kind of work-around if SGE provides me a way to declare that a specific job (or jobs in a specific queue) always needs to run with a specific user's rights.

  • My computer freezes irregularly

    - by Manhim
    My computer started to freeze at irregular times for 3 weeks now. Please note that this question change with each things that i try. (For additional details) What happens My computer freezes, the video stops. (No graphic glitches, it just stops) Sound keeps playing up to some time (Usually 10-30 seconds) then stops playing. Sometimes, randomly, the screen on my G-15 keyboard flickers and I see caracters not at the right places. Usually happens for about 1-2 seconds and a bit before my computer freezes. I have to keep the power button pressed for 4 seconds to shut my computer down. I still hear my hard drives and fans working. Sometimes it works with no problems for a full day, some other times it just keeps freezing each time I restart my computer and I have to leave it for the rest of the day. Sometimes my mouse freezes for a fraction of a second (Like 0.01 to 0.2 seconds) quite randomly, usually before it freezes. No errors spotted by the "Action center" unlike when I had problems with my last video card on this system (Driver errors). My G-15 LCD screen also freezes. Sometimes my G-15 LCD screen flickers and caracters gets caried around temporary under heavy load. Now, most of the times, the BIOS hard disks boot order gets reversed for some reason and I have to put it to the right one and save each times I boot. (Might be unrelated, not sure, but it first started yesterday) Sometimes the BIOS doesn't detect my 750GB hard drive plugged in SATA1. What I did so far I have had similar problems in the past and I had changed my hard drive (It was faulty), so I tested my software RAID-0 array and it was faulty so I changed it. (I reinstalled Windows 7 with this part). I also tested with unplugging my secondary hard drive. My CPU was running at about 100 degree Celsius, I removed the dust between the fans and the heatsink and it's now between 45-55. I ran a CPU stress-test and it didn't freeze during the tests (using Prime95 on all cores) Ran a memory test (using memtest86+) for a single pass and there were no errors. Ran a GPU stress test with ati-tools and furmark and it didn't freeze during the tests. (No artefacts either) I had troubles with my graphic card when I got it, but I think that it got fixed with a driver update. I checked the voltages in my BIOS setup and they all seemed ok (±0.2 I think). I have ran on the computer without problems with Fedora 15 on an external hard drive (Appart that it couldn't load Gnome 3 and was reverting to Gnome 2, didn't want to install drivers since I use it on multiple computers) I used it to backup my files from the raid array to my 1TB hard drive for the reinstallation of Windows. (So the crashes only happenned on Windows) [The external hard drive is plugged directly on a SATA port] I contacted EVGA (My graphic card vendor) and pointed them on this question, I'm looking for an answer. Ran sensors on Fedora 15 and got this output: http://pastebin.com/0BHJnAvu Ran 6 short different CPU stress test on Fedora 15 (Haven't found any complete stress testers for Linux) and it didn't crash. Changed the thermal paste to some Artic Silver 5 for my CPU and stress tested the CPU, temperature was at 50 idle, then 64 highest and slowly went down to 62 during the test. Ran some stress testing with a temporary graphic card and it went ok. Ran furmark stress test with my original graphic card and it freezed again. GPU had a temp of 74C, a CPU temp of 58C and a mobo temp of 40C or 45C (Dunno which one it is from SpeedFan). Ran a furmark stress test and a CPU stress test at the same time, results: http://pastebin.com/2t6PLpdJ I have been using my computer without stressing it for about 2 hours now and no crashes yet. I also have disabled the AMD Cool'n'quiet function on the BIOS for a more regular power to the CPU. When I ran Furmark without C'n'q my computer didn't freeze but I had a "Driver Kernel Error" that have recovered (And Furmark crashed) all that while running a CPU stress test. The computer eventually frozed without me being at it, but this time my screen just went on sleep and I couldn't wake it. Using the stability tester in nTune my computer freezed again (In the same manner as before). I notived that Speedfan gives me a -12V of -16.97V and a -5V of -8.78V. I wonder if these numbers are reliable and if they are good or bad. I have swapped my G-15 with another basic USB keyboard (HP) and I have ran furmark for about 10 minutes with a CPU stability test running each 60 seconds for 30 seconds and my computer haven't crashed yet. Ran some more extended tests without my G-15 and it freezed like it usually do. Removed the nForce Hard disk controler. Disabled command queuing in the NVIDIA nForce SATA Controller for both port 0 and port 1 (Errors from the logs) Used CPUID HwMonitor, here are the voltages: http://pastebin.com/dfM7p4jV Changed some configurations in the motherboard BIOS: Disabled PEG Link Mode, Changed AI Tuning to Standard, Disabled the 1394 Controller, Disabled HD Audio, Disabled JMicron RAID controller and Disabled SATA Raid. When it happens When I play video games (Mostly) When I play flash games (Second most) When I'm looking at my desktop background (It rarely happens when I have a window open, but it does, sometimes) When my Graphic card and my CPU are stressed. Sometimes when my Graphic card is stressed. Never happenned while stressing only the CPU. Sometimes when my CPU is stressed. Specs Windows Seven x64 Home Premium Motherboard: M2N-SLI Deluxe CPU: AMD Phenom 9950 x2 @ 2.6GHz Memory: Kingston 4x2GB Dual Channel (Pretty basic memory sticks) Hard drives: Was 2x250GB (Western digital caviar) in raid-0 + 1TB (WD caviar black), I replaced the raid array with a 750GB (WD caviar black) [Yes I removed the array from the raid configurations] 750W Power supply No overcloking. Ever. There have been some power-downs like 4-5 weeks ago, but the problem didn't start immediately after. (I wasn't home, so my computer got shut-down) Event logs (Warnings, errors and critical errors) for the last 24 hours: http://pastebin.com/Bvvk31T7 My current to-try list Reinstall the drivers and software 1 by 1 and do extensive stress testing between each. Update the BIOS firmware to the most recent stable one. Change my motherboard. Status updates Keeping only the last 3 (28/06 04pm) More stress testing and still pass the tests. (28/06 03pm) Been stress testing for 10 minute straight now and 5 minutes with both CPU and GPU being stressed at the same time. (28/06 03pm) Stress-testing right now, so far no problems. A little hope Tests with Furmark and Prime95. Testing Windows bare-bone: 30 Minutes stress, no freeze. Installing an Anti-virus and some software, restarting computer. Testing with Anti-virus and some software (No drivers installed): 30 Minutes stress, no freeze. Installing audio drivers, restarting computer. Testing with the audio drivers: 30 Minutes stress, no freeze. Installing the latest graphic drivers from EVGA's website (without 3d vision since I don't use it), restarting computer. Testing with the graphic drivers: 30 Minutes stress, no freeze. Configuring Windows to my liking and installing more softwares. In this situation, how can I successfully pin-point the current hardware problem? (If it's a hardware problem) Because I don't really have the budget to just forget and replace everything. I also don't really have hardware to test-replace current hardware.

  • MAC addresses on dual-NIC mainboards

    - by Tom O'Connor
    Here's a weird problem. We've got a number of devices with dual-NIC mainboards. Some are Realtek NICs, which suck. Some are Intel e1000s, which don't. I've just noticed on 2 machines, one is an Intel NIC, one is a Realtek, that when I put the MAC address of one machine into the dhcpd.conf file on our DHCP server to get it to PXE boot the machine into a rebuild environment, initially everything is fine. The server gets a DHCP allocation, and PXE boots into the Ubuntu preseed enviroment. On one or two machines, it gets as far as Ubuntu's DHCP network configuration, and fails. If i pull up a busybox shell (on tty2 on the installing machine), and run ip link, I can see that the UP flag is set on the other NIC. Here's some stuff. host xeon16-ghz240-gb48-node1 { hardware ethernet BC:AE:C5:07:1F:18; filename "pxelinux.0"; next-server 192.168.123.80; } That's what's in dhcpd.conf This is what ip link on the evil machine looks like. Only one NIC is actually connected (deliberately). As you can see, the NIC that's in the dhcpd config, is not marked as UP, and the link that is UP, isn't the one in DHCP. So far I've seen this on two brands of dual-NIC configuration. Does anyone know 1) what's causing it, and b) What we can do about it?

  • Need a VM for running a PHP Sandbox

    - by Phani
    I am working on Web application honeypot. It collects PHP files it receives (as part of an RFI attack) and runs them in order to return the result back to the attacker. The aim is to coax the bad guy into going further into his attack. Based on the answers to my SO question, I am looking at using VMs for running the PHP Sandbox. The honeypot itself consists of Python code and will be running in a Linux environment (preferably Ubuntu-like). These are some of the requirements: The VM should be a light weight as possible. We are going to distribute the code around and many people are going to use the VM along with the Python based honeypot. So, the installation and configuration should not be too difficult. The guest system would also be Linux as we are going to distribute the VM image around. It should be possible for the Python code outside to talk to the guest system. It would be passing on the PHP file to the guest system and will get the output result from it. It should be possible to automate the initial configuration of the VM (such as allocation of RAM etc.) I would like to randomize these settings in order to make the sandbox less 'fingerprintable' I have looked at OpenVZ and KVM so far. Are there any other VMs that I might look at? What do you recommend?

  • ram monitoring on linux

    - by user40157
    I would like to monitor the ram of two linux systems (Ubuntu and Red Hat). I realize I can run memtest86 from boot to diagnose bad ram. But are there are any solutions to monitor ram while the system is still running. I'm sort of thinking a daemon that writes and reads back from random unused memory. Anybody seen something like this before?

  • Performance issues concurrently running MySQL and MS SQL Sever

    - by pacifika
    We're considering installing MySQL on the same database server that has been running MS SQL Server. From my research there are no technical issues running both concurrently, but I am worried that the performance will be affected. Is by default SQL Server set up to use all available memory for example? What should I look out for? Thanks

  • EC2 Filesystem / Files stored on the wrong partiton after launching new instance from AMI

    - by Philip Isaacs
    Today I set up a new EC2 Instance from and AMI I created from an older EC2 instance. When I launched the new instance I took the AMI that was on a small instance and launched with a medium instance. From what I can tell this is pretty standard stuff. But here's the stang part. According to AWS these are the differences Small Instance (Default) 1.7 GB of memory, 1 EC2 Compute Unit (1 virtual core with 1 EC2 Compute Unit), 160 GB of local instance storage, 32-bit or 64-bit platform Medium Instance 3.75 GB of memory, 2 EC2 Compute Units (1 virtual core with 2 EC2 Compute Units each), 410 GB of local instance storage, 32-bit or 64-bit platform Okay now here's where I'm having an issue. I when I log into the new bigger instance it still reports only having 1.7 GB of ram. The other strange part is that all my old partitions are still their in the same configurations. I see a new larger partition /mnt which is essential empty. Filesystem Size Used Avail Use% Mounted on /dev/sda1 7.9G 5.9G 1.6G 79% / none 846M 120K 846M 1% /dev none 879M 0 879M 0% /dev/shm none 879M 76K 878M 1% /var/run none 879M 0 879M 0% /var/lock none 879M 0 879M 0% /lib/init/rw /dev/sda2 335G 195M 318G 1% /mnt /dev/sdf 16G 9.9G 5.1G 67% /var2 This EC2 is a web server and I was serving files off the /var2 directory but for some reason the instance is storing everything on / Okay here's what I'd like to do. Move all my website files to /mnt and have the web server point to that. Any suggestions? If it helps here is what my fstab looks like as well. root@myserver:/var# mount -l /dev/sda1 on / type ext3 (rw) [cloudimg-rootfs] proc on /proc type proc (rw,noexec,nosuid,nodev) none on /sys type sysfs (rw,noexec,nosuid,nodev) none on /sys/kernel/debug type debugfs (rw) none on /sys/kernel/security type securityfs (rw) none on /dev type devtmpfs (rw,mode=0755) none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) none on /dev/shm type tmpfs (rw,nosuid,nodev) none on /var/run type tmpfs (rw,nosuid,mode=0755) none on /var/lock type tmpfs (rw,noexec,nosuid,nodev) none on /lib/init/rw type tmpfs (rw,nosuid,mode=0755) /dev/sda2 on /mnt type ext3 (rw) /dev/sdf on /var2 type ext4 (rw,noatime) I hope this question makes sense. Basically i want my old files on this new partition. Thanks in advance
