  • Linux configurations that would affect Java memory usage?

    - by wmacura
    Hi, Background: I have a set of java background workers I start as part of my webapp. I develop locally on Ubuntu 10.10 and deploy to an Ubuntu 10.04LTS server (a media temple (ve) instance). They're both running the same JVM: Sun JVM 1.6.0_22-b04. As part of the initialization script each worker is started with explicit Xmx, Xms, and XX:MaxPermGen settings. Yet somehow locally all 10 workers use 250MB, while on the server they use more than 2.7GB. I don't know how to begin to track this down. I thought the Ubuntu (and thus, kernel) version might make a difference, but I tried an old 10.04 VM and it behaves as expected. I've noticed that the machine does not seem to ever use memory for buffer or cache (according to htop), which seems a bit strange, but perhaps normal for a server? (edited) Some info: (server) root@devel:/app/axir/target# uname -a Linux devel 2.6.18-028stab069.5 #1 SMP Tue May 18 17:26:16 MSD 2010 x86_64 GNU/Linux (local) wiktor@beastie:~$ uname -a Linux beastie 2.6.35-25-generic #44-Ubuntu SMP Fri Jan 21 17:40:44 UTC 2011 x86_64 GNU/Linux (edited) Comparing PS output: (ps -eo "ppid,pid,cmd,rss,sz,vsz") PPID PID CMD RSS SZ VSZ (local) 1588 1615 java -cp axir-distribution. 25484 234382 937528 1615 1631 java -cp /home/wiktor/Code/ 83472 163059 652236 1615 1657 java -cp /home/wiktor/Code/ 70624 89135 356540 1615 1658 java -cp /home/wiktor/Code/ 37652 77625 310500 1615 1669 java -cp /home/wiktor/Code/ 38096 77733 310932 1615 1675 java -cp /home/wiktor/Code/ 37420 61395 245580 1615 1684 java -cp /home/wiktor/Code/ 38000 77736 310944 1615 1703 java -cp /home/wiktor/Code/ 39180 78060 312240 1615 1712 java -cp /home/wiktor/Code/ 38488 93882 375528 1615 1719 java -cp /home/wiktor/Code/ 38312 77874 311496 1615 1726 java -cp /home/wiktor/Code/ 38656 77958 311832 1615 1727 java -cp /home/wiktor/Code/ 78016 89429 357716 (server) 22522 23560 java -cp axir-distribution. 24860 285196 1140784 23560 23585 java -cp /app/axir/target/a 100764 161629 646516 23560 23667 java -cp /app/axir/target/a 72408 92682 370728 23560 23670 java -cp /app/axir/target/a 39948 97671 390684 23560 23674 java -cp /app/axir/target/a 40140 81586 326344 23560 23739 java -cp /app/axir/target/a 39688 81542 326168 They look very similar. In fact, the question now is why, if I add up the virtual memory usage on the server (3.2GB) does it more closely reflect 2.4GB of memory used (according to free), yet locally the virtual memory used adds up to a much more substantial 4.7GB but only actually uses ~250MB. It seems that perhaps memory isn't being shared as aggressively. (if that's even possible) Thank you for your help, Wiktor

  • Effect of suffixes in memory to cache operations

    - by tur1ng
    In x86 GNU Assembler there are different suffixes for memory related operations. E.g.: movb, movs, movw, movl, movq, movt(?) Now my question is the following: Does the suffix has ANY effect on how the processor is getting the data out of main memory or will always be one or more 32-bit (x86) chunks loaded into the cache ? What are the effects beside the memory access?

  • double click and select the path(including '/') in Terminal.app

    - by mash
    I'm using Terminal.app on Mac OS10.6.3, with gnu screen and zsh. What I want to do is, see pwd(or an URL) in Terminal.app and double click on it, and select the whole path, to copy and paste after that. But what I get now is a single directory name, because '/' is not treated as a word. I found that iTerm has a setting to change it(iTerm - Preferences - Mouse - Characters considered part of a word), but is there any way to do this on my environment?

  • Example of xargs' -x option in action

    - by Ole Tange
    GNU xargs has option '-x'. The man page says: -x Exit if the size (see the -s option) is exceeded. But xargs seems to not care if -x is set or not. I have been unable to make an example in which the -x has any effect at all. Please provide two examples in which the only difference is an added -x and that produce different output.

  • C Language Standard Collections Where Are They?

    - by flaxeater
    I have committed to learning C now, I'm good with Python/PHP/Bash but I've decided I'm limited by not being fluent in C. However I cannot imagine working in a language without lists and hashes, maybe I'm just jumping a gun, but surely there are 'standard' collection libraries. I do not see any in the GNU standard lib though, any suggestions?

  • Is there a good extension for SVN in Emacs?

    - by allyourcode
    I've tried psvn.el, but the command to diff the file you're currently looking at is just hideous: M-x svn-file-show-svn-diff. I tried installing vc-svn.el, but couldn't get that working on my version of Emacs: GNU Emacs 21.3.1 (i386-mingw-nt5.1.2600) of 2004-03-10 on NYAUMO. The emacs wiki page, which mainly focuses on vc-svn.el, seems to be horribly out of date, as many of the links do not work.

  • Finding where varables have been declared in what file?

    - by robUK
    Hello, GNU Emacs 23.1.1 I am maintaining someones code. There are many files and directories for the headers and source files. I am wondering if there is a easy way to use emacs that when I highlight a variable name I can go straight to where it is declared? Some of the structures I am working in are declared in other header files, rather than go searching for them, I just want to be taken straight to them. Many thanks for any suggestions,

  • Getting the callers of a specific function

    - by robUK
    Hello, GNU Emacs 23.1.1 I am just wondering is there any feature in emacs where I can find out what functions call a specific function. In my code, I normally have to do a search on the function name to see what functions calls it. It would be nice if I could display all the names of the functions where this specific function is being called from. many thanks for any suggestions,

  • Must declare function prototype in C?

    - by Mohit Deshpande
    I am kind of new to C (I have prior Java, C#, and some C++ experience). In C, is it necessary to declare a function prototype or can the code compile without it? Is it good programming practice to do so? Or does it just depend on the compiler? (I am running Ubuntu 9.10 and using the GNU C Compiler, or gcc, under the Code::Blocks IDE)

  • Listing C Constants/Macros

    - by ZJR
    Is there a way to make the GNU C Preprocessor, cpp (or some other tool) list all available macros and their values at a given point in a C file? I'm looking for system-specific macros while porting a program that's already unix savvy and loading a sparse bunch of unix system files. Just wondering if there's an easier way than going hunting for definitions.

  • Java 1.7ea: Files.probeContentType(path) returns null

    - by Cybertizzen
    Hi, I'm having a bit of a strange problem with an application using the Files.probeContentType(path)-method to test for file type: On both my Ubuntu and Fedora systems, it works fine, but when moved to a RedHat Enterprise server (2.6.18-194.el5 #1 x86_64 x86_64 x86_64 GNU/Linux), it only returns null. I'm using java 7 early access (1.7.0-ea-b84). I have to use this version due to functionality that isn't included in 1.6. Does anyone have an idea of what might be the problem here?

  • stunnel crashing

    - by Jay
    I'm trying to use stunnel to secure a legacy application's communications. I can't seem to get it setup and working. Can anyone provide any hints where I'm going wrong? Here's what I'm trying to accomplish: A windows service on a client machine connects to a server on port 7000 using TCP. I'd like to encrypt the communication between client and server. Here's what I've tried: Created a new server that accepts ssl connections on port 7443. Got a certificate for the server and installed it. That seems to work with my test setup. Installed stunnel on my windows machine (version 7.43 from the distribution archive file). Installed libssl32.dll and libeay32.dll in the same directory as stunnel.exe ( from the openssl-0.9.8h-1 binary distribution). Installed it as a service using "stunnel -install" Configured stunnel as follows: debug=7 output=C:\p4\internal\Utility\Proxy\proxy.log service=Proxy taskbar=no [exchange] accept=7000 client=yes connect=proxy.blah.com:7443 I changed my hosts file to trick the old application into connecting through stunnel: server.blah.com 127.0.0.1 # when client looks up server it goes to stunnel proxy.blah.com IP-address-of-server.blah.com # stunnel connects to new server "server.blah.com" now resolves to the machine it's running on (i.e. stunnel). "proxy.blah.com" goes to the real server. stunnel should connect to the server. I start the stunnel service and try to connect. It looks like it's working but the stunnel service just shuts down with no message. 2010.04.19 13:16:21 LOG5[4924:3716]: stunnel 4.33 on x86-pc-mingw32-gnu with OpenSSL 0.9.8h 28 May 2008 2010.04.19 13:16:21 LOG5[4924:3716]: Threading:WIN32 SSL:ENGINE Sockets:SELECT,IPv6 2010.04.19 13:16:49 LOG5[4924:3748]: Service exchange accepted connection from 127.0.0.1:4134 2010.04.19 13:16:49 LOG6[4924:3748]: connect_blocking: connecting x.80.60.32:7443 2010.04.19 13:16:49 LOG5[4924:3748]: connect_blocking: connected x.80.60.32:7443 2010.04.19 13:16:49 LOG5[4924:3748]: Service exchange connected remote server from x.253.120.19:4135 2010.04.19 13:20:24 LOG5[3668:3856]: Reading configuration from file stunnel.conf 2010.04.19 13:20:24 LOG7[3668:3856]: Snagged 64 random bytes from C:/.rnd 2010.04.19 13:20:24 LOG7[3668:3856]: Wrote 1024 new random bytes to C:/.rnd 2010.04.19 13:20:24 LOG7[3668:3856]: RAND_status claims sufficient entropy for the PRNG 2010.04.19 13:20:24 LOG7[3668:3856]: PRNG seeded successfully 2010.04.19 13:20:24 LOG7[3668:3856]: SSL context initialized for service exchange 2010.04.19 13:20:24 LOG5[3668:3856]: Configuration successful 2010.04.19 13:20:24 LOG5[3668:3856]: No limit detected for the number of clients 2010.04.19 13:20:24 LOG7[3668:3856]: FD=312 in non-blocking mode 2010.04.19 13:20:24 LOG7[3668:3856]: Option SO_REUSEADDR set on accept socket 2010.04.19 13:20:24 LOG7[3668:3856]: Service exchange bound to 0.0.0.0:7000 2010.04.19 13:20:24 LOG7[3668:3856]: Service exchange opened FD=312 2010.04.19 13:20:24 LOG5[3668:3856]: stunnel 4.33 on x86-pc-mingw32-gnu with OpenSSL 0.9.8h 28 May 2008 2010.04.19 13:20:24 LOG5[3668:3856]: Threading:WIN32 SSL:ENGINE Sockets:SELECT,IPv6 2010.04.19 13:21:02 LOG7[3668:4556]: Service exchange accepted FD=372 from 127.0.0.1:4156 2010.04.19 13:21:02 LOG7[3668:4556]: Creating a new thread 2010.04.19 13:21:02 LOG7[3668:4556]: New thread created 2010.04.19 13:21:02 LOG7[3668:3756]: Service exchange started 2010.04.19 13:21:02 LOG7[3668:3756]: FD=372 in non-blocking mode 2010.04.19 13:21:02 LOG5[3668:3756]: Service exchange accepted connection from 127.0.0.1:4156 2010.04.19 13:21:02 LOG7[3668:3756]: FD=396 in non-blocking mode 2010.04.19 13:21:02 LOG6[3668:3756]: connect_blocking: connecting x.80.60.32:7443 2010.04.19 13:21:02 LOG7[3668:3756]: connect_blocking: s_poll_wait x.80.60.32:7443: waiting 10 seconds 2010.04.19 13:21:02 LOG5[3668:3756]: connect_blocking: connected x.80.60.32:7443 2010.04.19 13:21:02 LOG5[3668:3756]: Service exchange connected remote server from x.253.120.19:4157 2010.04.19 13:21:02 LOG7[3668:3756]: Remote FD=396 initialized 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): before/connect initialization 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 write client hello A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 read server hello A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 read server certificate A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 read server done A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 write client key exchange A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 write change cipher spec A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 write finished A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 flush data 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 read finished A The client thinks the connection is closed: No connection could be made because the target machine actively refused it 127.0.0.1:7000 at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.Connect(EndPoint remoteEP) at Service.ConnUtility.Connect() Any suggestions?

Did I mention the root filesystem is mounted over NFS. However it's mounted 'defaults,nosuid', which should include execute. Also I am able to run many other programmes from that mounted drive /proc/cpuinfo: processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Xeon(TM) CPU 3.00GHz stepping : 1 cpu MHz : 2992.692 cache size : 1024 KB fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu tsc msr pae mce cx8 apic mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm syscall nx lm constant_tsc pni monitor ds_cpl cid cx16 xtpr bogmips : 5989.55 clflush size : 64 cache_alignment : 128 address sizes : 36 bits physical, 48 bits virtual power management: Example of a file that I can run I can run other programmes on that mounted filesystem on that server.

  • ssh authentication nfs

    - by user40135
    Hi all I would like to do ssh from machine "ub0" to another machine "ub1" without using passwords. I setup using nfs on "ub0" but still I am asked to insert a password. Here is my scenario: * machine ub0 and ub1 have the same user "mpiu", with same pwd, same userid, and same group id * the 2 servers are sharing a folder that is the HOME directory for "mpiu" * I did a chmod 700 on the .ssh * I created a key using ssh-keygene -t dsa * I did "cat id_dsa.pub authorized_keys". On this last file I tried also chmod 600 and chmod 640 * off course I can guarantee that on machine ub1 the user "shared_user" can see the same fodler that wes mounted with no problem. Below the content of my .ssh folder Code: authorized_keys id_dsa id_dsa.pub known_hosts After all of this calling wathever function "ssh ub1 hostname" I am requested my password. Do you know what I can try? I also UNcommented in the ssh_config file for both machines this line IdentityFile ~/.ssh/id_dsa I also tried ssh -i $HOME/.ssh/id_dsa mpiu@ub1 Below the ssh -vv Code: OpenSSH_5.1p1 Debian-3ubuntu1, OpenSSL 0.9.8g 19 Oct 2007 OpenSSH_5.1p1 Debian-3ubuntu1, OpenSSL 0.9.8g 19 Oct 2007 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to ub1 [192.168.2.9] port 22. debug1: Connection established. debug2: key_type_from_name: unknown key type '-----BEGIN' debug2: key_type_from_name: unknown key type '-----END' debug1: identity file /mirror/mpiu/.ssh/id_dsa type 2 debug1: Checking blacklist file /usr/share/ssh/blacklist.DSA-1024 debug1: Checking blacklist file /etc/ssh/blacklist.DSA-1024 debug1: Remote protocol version 2.0, remote software version lshd-2.0.4 lsh - a GNU ssh debug1: no match: lshd-2.0.4 lsh - a GNU ssh debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.1p1 Debian-3ubuntu1 debug2: fd 3 setting O_NONBLOCK debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug2: kex_parse_kexinit: diffie-hellman-group-exchange-sha256,diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1 debug2: kex_parse_kexinit: ssh-rsa,ssh-dss debug2: kex_parse_kexinit: aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,arcfour128,arcfour256,arcfour,aes192-cbc,aes256-cbc,[email protected],aes128-ctr,aes192-ctr,aes256-ctr debug2: kex_parse_kexinit: aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,arcfour128,arcfour256,arcfour,aes192-cbc,aes256-cbc,[email protected],aes128-ctr,aes192-ctr,aes256-ctr debug2: kex_parse_kexinit: hmac-md5,hmac-sha1,[email protected],hmac-ripemd160,[email protected],hmac-sha1-96,hmac-md5-96 debug2: kex_parse_kexinit: hmac-md5,hmac-sha1,[email protected],hmac-ripemd160,[email protected],hmac-sha1-96,hmac-md5-96 debug2: kex_parse_kexinit: none,[email protected],zlib debug2: kex_parse_kexinit: none,[email protected],zlib debug2: kex_parse_kexinit: debug2: kex_parse_kexinit: debug2: kex_parse_kexinit: first_kex_follows 0 debug2: kex_parse_kexinit: reserved 0 debug2: kex_parse_kexinit: diffie-hellman-group14-sha1,diffie-hellman-group1-sha1 debug2: kex_parse_kexinit: ssh-rsa,spki-sign-rsa debug2: kex_parse_kexinit: aes256-cbc,3des-cbc,blowfish-cbc,arcfour debug2: kex_parse_kexinit: aes256-cbc,3des-cbc,blowfish-cbc,arcfour debug2: kex_parse_kexinit: hmac-sha1,hmac-md5 debug2: kex_parse_kexinit: hmac-sha1,hmac-md5 debug2: kex_parse_kexinit: none,zlib debug2: kex_parse_kexinit: none,zlib debug2: kex_parse_kexinit: debug2: kex_parse_kexinit: debug2: kex_parse_kexinit: first_kex_follows 0 debug2: kex_parse_kexinit: reserved 0 debug2: mac_setup: found hmac-md5 debug1: kex: server-client 3des-cbc hmac-md5 none debug2: mac_setup: found hmac-md5 debug1: kex: client-server 3des-cbc hmac-md5 none debug2: dh_gen_key: priv key bits set: 183/384 debug2: bits set: 1028/2048 debug1: sending SSH2_MSG_KEXDH_INIT debug1: expecting SSH2_MSG_KEXDH_REPLY debug1: Host 'ub1' is known and matches the RSA host key. debug1: Found key in /mirror/mpiu/.ssh/known_hosts:1 debug2: bits set: 1039/2048 debug1: ssh_rsa_verify: signature correct debug2: kex_derive_keys debug2: set_newkeys: mode 1 debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug2: set_newkeys: mode 0 debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug2: service_accept: ssh-userauth debug1: SSH2_MSG_SERVICE_ACCEPT received debug2: key: /mirror/mpiu/.ssh/id_dsa (0xb874b098) debug1: Authentications that can continue: password,publickey debug1: Next authentication method: publickey debug1: Offering public key: /mirror/mpiu/.ssh/id_dsa debug2: we sent a publickey packet, wait for reply debug1: Authentications that can continue: password,publickey debug2: we did not send a packet, disable method debug1: Next authentication method: password mpiu@ub1's password: I hangs here!

  • Incorrect gzipping of http requests, can't find who's doing it

    - by Ned Batchelder
    We're seeing some very strange mangling of HTTP responses, and we can't figure out what is doing it. We have an app server handling JSON requests. Occasionally, the response is returned gzipped, but with incorrect headers that prevent the browser from interpreting it correctly. The problem is intermittent, and changes behavior over time. Yesterday morning it seemed to fail 50% of the time, and in fact, seemed tied to one of our two load-balanced servers. Later in the afternoon, it was failing only 20 times out of 1000, and didn't correlate with an app server. The two app servers are running Apache 2.2 with mod_wsgi and a Django app stack. They have identical Apache configs and source trees, and even identical packages installed on Red Hat. There's a hardware load balancer in front, I don't know the make or model. Akamai is also part of the food chain, though we removed Akamai and still had the problem. Here's a good request and response: * Connected to example.com (97.7.79.129) port 80 (#0) > POST /claim/ HTTP/1.1 > User-Agent: curl/7.19.7 (x86_64-pc-linux-gnu) libcurl/7.19.7 OpenSSL/0.9.8k zlib/1.2.3.3 libidn/1.15 > Host: example.com > Accept: */* > Referer: http://example.com/apps/ > Accept-Encoding: gzip,deflate > Content-Length: 29 > Content-Type: application/x-www-form-urlencoded > } [data not shown] < HTTP/1.1 200 OK < Server: Apache/2 < Content-Language: en-us < Content-Encoding: identity < Content-Length: 47 < Content-Type: application/x-javascript < Connection: keep-alive < Vary: Accept-Encoding < { [data not shown] * Connection #0 to host example.com left intact * Closing connection #0 {"msg": "", "status": "OK", "printer_name": ""} And here's a bad one: * Connected to example.com (97.7.79.129) port 80 (#0) > POST /claim/ HTTP/1.1 > User-Agent: curl/7.19.7 (x86_64-pc-linux-gnu) libcurl/7.19.7 OpenSSL/0.9.8k zlib/1.2.3.3 libidn/1.15 > Host: example.com > Accept: */* > Referer: http://example.com/apps/ > Accept-Encoding: gzip,deflate > Content-Length: 29 > Content-Type: application/x-www-form-urlencoded > } [data not shown] < HTTP/1.1 200 OK < Server: Apache/2 < Content-Language: en-us < Content-Encoding: identity < Content-Type: application/x-javascript < Content-Encoding: gzip < Content-Length: 59 < Connection: keep-alive < Vary: Accept-Encoding < X-N: S < { [data not shown] * Connection #0 to host example.com left intact * Closing connection #0 ?V?-NW?RPR?QP*.I,)-???A??????????T??Z? ??/ There are two things to notice about the bad response: It has two Content-Encoding headers, and the browsers seem to use the first. So they see an identity encoding header, and gzipped content, so they can't interpret the response. The bad response has an extra "X-N: S" header. Perhaps if I could find out what intermediary adds "X-N: S" headers to responses, I could track down the culprit...

  • Severe mysqldump performance degradation using Centos Linux, 8GB PAE and MySQL 5.0.77

    - by Duncan Harris
    We use MySQL 5.0.77 on CentOS 5.5 on VMWare: Linux dev.ic.soschildrensvillages.org.uk 2.6.18-194.11.4.el5PAE #1 SMP Tue Sep 21 05:48:23 EDT 2010 i686 i686 i386 GNU/Linux We have recently upgraded from 4GB RAM to 8GB. When we did this the time of our mysqldump overnight backup jumped from under 10 minutes to over 2 hours. It also caused unresponsiveness on our plone based web site due to database load. The dump is using the optimized mysqldump format and is spooled directly through a socket to another server. Any ideas on what we could do to fix gratefully appreciated. Would a MySQL upgrade help? Anything we can do to MySQL config? Anything we can do to Linux config? Or do we have to add another server or go to 64-bit? We ran a previous (non-virtual) server on 6GB PAE and didn't notice a similar issue. This was on same MySQL version, but Centos 4.4.
