Hi Willy, Sorry for give your feedback late. I test it several days and it does not work with the new two patchs. It hang two times one day. It still get the errors as follows, haproxy[8728]: segfault at 000000001e90f000 rip 0000003ef9c7c51a rsp 00007fff80e29208 error 6 haproxy[18325]: segfault at 000000001e397000 rip 0000003ef9c7c373 rsp 00007fff071afbd8 error 4 haproxy[19660]: segfault at 000000001067a000 rip 0000003ef9c7c506 rsp 00007ffff0703288 error 6 haproxy[19955]: segfault at 0000000006a2e000 rip 0000003ef9c7c3df rsp 00007fff15517608 error 4 haproxy[20180]: segfault at 000000000958b000 rip 0000003ef9c7c4c8 rsp 00007fff64b3ecb8 error 6
do you think it maybe caused by enable the cookie and appsession together? cookie HTTPSERVERID insert nocache indirect appsession JSESSIONID len 34 timeout 1h should I disable the cookie and just enable the appsession to test it? If it is cause by memory shortage, do you know how to disable the memory limitation? Here is basic information of my server. # uname -a Linux 239488-web3.239488-web3.icebreaker.mobi 2.6.18-194.17.1.el5 #1 SMP Mon Sep 20 07:12:06 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux # ulimit -a core file size (blocks, -c) unlimited data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 139264 max locked memory (kbytes, -l) 32 max memory size (kbytes, -m) unlimited open files (-n) 65535 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 10240 cpu time (seconds, -t) unlimited max user processes (-u) unlimited virtual memory (kbytes, -v) unlimited file locks (-x) unlimited Thanks for you help. :) Hogan On Sat, Nov 20, 2010 at 12:58 PM, Willy Tarreau <[email protected]> wrote: > Hi Hogan, > > [I removed Cyril from the CC, he might get bored and he's on the list] > > On Sat, Nov 20, 2010 at 10:46:53AM +0800, Hogan Yu wrote: > > Hi Willy, > > I update all your suggestion > > > > 1. compile with USE_PCRE=1 > > 2. set ulimit -m unlimited > > 3. use the two patches > > perfect. > > > Here is my ulimit -a list > > > > # ulimit -a > > core file size (blocks, -c) unlimited > > data seg size (kbytes, -d) unlimited > > scheduling priority (-e) 0 > > file size (blocks, -f) unlimited > > pending signals (-i) 139264 > > max locked memory (kbytes, -l) 32 > > max memory size (kbytes, -m) unlimited > > open files (-n) 65535 > > pipe size (512 bytes, -p) 8 > > POSIX message queues (bytes, -q) 819200 > > real-time priority (-r) 0 > > stack size (kbytes, -s) 10240 > > cpu time (seconds, -t) unlimited > > max user processes (-u) unlimited > > virtual memory (kbytes, -v) unlimited > > file locks (-x) unlimited > > > > do you think I need to change the max locked memory to a bigger value? > > No, because we're not using any locked memory.
