Description Konstantin Arkhipov (RETIRED) gentoo-dev 2005-03-21 00:56:04 UTC 
dev-php/eaccelerator segfaults on my production dual opteron box.

php is working as cgi (dev-php/php-cgi-4.3.10), web server - www-server/nginx-0.1.25, application - phpAdsNew

problem occurs under heavy load only and, unfortunately, i can't reproduce it on my amd64 3200+ dev-box. when eaccelerator disabled - everything goes smooth and fine.

even worse: i can't debug it on that box, because it's production server

logs:
Mar 21 11:48:58 z80 kernel: php-cgi[19104]: segfault at 000000000000007f rip 00000000005b47c5 rsp 00007fffffffed80 error 6

Reproducible: Always
Steps to Reproduce:
1. emerge dev-php/php-cgi-4.3.10
2. emerge dev-php/eaccelerator
3. make heavy load on php-applications

Actual Results:  
logs are full of segfaults

Expected Results:  
everything works ok

The eAccelerator bug database (http://sourceforge.net/tracker/?group_id=122249&atid=692864) is full of reports about segfaults.

Comment 3 Konstantin Arkhipov (RETIRED) gentoo-dev 2005-05-06 07:34:17 UTC 
seems to be fixed in latest cvs. at least - works for me.
