segfaults when using XCache 2.0.1 under heavy load
|Reported by:||boxdev||Owned by:||moo|
Some of our machines have XCache 2.0.1 installed. In case this helps with troubleshooting XCache 3.0.x, here are some stack traces.
We would appreciate your feedback on what other data we can gather.
Version of XCache: php-xcache-2.0.1-5.4.13_box2.el6.x86_64
Version of PHP: php-5.4.13-1.el6.x86_64
Version of Apache: httpd-2.2.15-15.sl6.1.x86_64
OS: Scientific Linux 6
Output of 'uname -a': Linux pod4201-upload01.pod.box.net 2.6.32-220.23.1.el6.x86_64 #1 SMP Mon Jun 18 09:58:09 CDT 2012 x86_64 x86_64 x86_64 GNU/Linux
Frequency of occurrence: Normally very low. But intermittently, every web server request results in a segfault.
xcache.readonly_protection = On
Once a server gets into the state where all requests result in a segfault, we bounce httpd and requests can be processed normally again.
