Edit report at https://bugs.php.net/bug.php?id=62929&edit=1 ID: 62929 Comment by: ahebert at pubnix dot net Reported by: sergiu dot ionescu at gmail dot com Summary: Segmentation fault on Zend Framework application Status: Open Type: Bug Package: *General Issues Operating System: Ubuntu 10.04.4 LTS PHP Version: PHP 5.3.16 Block user comment: N Private report: N New Comment: 1 day and no core dump after changing Magento session handling from file to database. In that case it might be related to the change to flock in 5.3.2. Good luck Previous Comments: ------------------------------------------------------------------------ [2012-10-09 16:53:55] ahebert at pubnix dot net I can confirm this issue happening in this situation: . FreeBSD 8.2-p2 amd64 . Compiled ports . PHP 5.4.6 (from ports) . Magento 1.5.1.0 The effect we're noticing is, in the /admin section of Magento, is that while you navigate, it will stop responding: . on the server side nothing is noticeable . after the usual 30s timeout you will get the page back . then you may or may not have a core dump Digging further, it seems to come from a flock issue since I can find this sequence in all my dumps. The stack at #28 is most likely the 30s timeout and the flock caused a dead lock. #27 0x00000000004481bb in just_die (sig=Variable "sig" is not available. ) at prefork.c:328 #28 <signal handler called> #29 0x000000080141f8fc in flock () from /lib/libc.so.7 More to come... ------------------------------------------------------------------------ [2012-08-30 17:03:22] sergiu dot ionescu at gmail dot com apc alone does not generate this. It's related to apc+Magento+a Multi-location module for Magento... That's why it's hard to give you a script to reproduce it. All i can say that the specific module uses allot of weird obfuscation: eval's and other stuff you don't necessarily need. ------------------------------------------------------------------------ [2012-08-30 16:39:29] laruence@php.net so, this is related to apc? ------------------------------------------------------------------------ [2012-08-30 16:13:15] sergiu dot ionescu at gmail dot com Setting apc.enable_cli=0 so far has eliminated the issue. I don't this fixed the underlying issue but at least it gets rid of the nasty exit code at the end on the script. ------------------------------------------------------------------------ [2012-08-28 08:04:19] laruence@php.net if I don't get a script to reproduce it, then I think,, I can do nothing.. since there is not much info can get from the backtrace ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
