ID: 43105 Comment by: marcus dot mueller at grintsch dot com Reported By: ian at onlineloop dot com Status: Assigned Bug Type: Apache2 related Operating System: Solaris 10 PHP Version: 5.2.5RC2-dev Assigned To: ab5602 New Comment:
As I stated above we have this issue on two Linux boxes with self-compiled PHP binaries. These were compiled using gcc! Previous Comments: ------------------------------------------------------------------------ [2007-11-28 16:36:24] ian at onlineloop dot com Coming back to the bug report here now. In the meantime some private emails were exchanged, including a pfiles output from Solaris showing that PHP had over 210,000 open files after 24 hours running on our servers. Within 48 hours (we let it go this far onyl once), apache/php eats around 12Gb of RAM and has between 170 and 220 child processes with over 230,000 open files. Under 5.1.6 the usage is more around 1.5-2Gb ram, and 30-70 child processes, with rarely more than 100 open files (only when we are really under load do we get to more than about 800 open files at any one time). A small patch was sent to me to try, however this has changed nothing. I was also asked to compile with gcc if possible, however this is not feasible as too many other things would have to be recompiled. Besides, we specifically went away from gcc because everything we had that was compiled with gcc was seg faulting all the time, however with the Sun Studio compiler suite, everything is stable. I seriously doubt this is an apache bug, why were things working with previous versions of PHP, and not this one? ------------------------------------------------------------------------ [2007-11-28 15:02:11] grknight at iwon dot com I am also experiencing this issue. We are running Apache 2.2.3 on Redhat EL 3 and recently tried to update to 5.2.5 from 5.2.3 to fix the security issues. The moment 5.2.5 was activated, connections failed to close in apache and resulted in hung processes. I also tried 5.2.4 with the same results. No configurations were changed nor PHP scripts. Something changed in the PHP processes that prevents the apxs2handler from exiting between 5.2.3 and 5.2.4. Configs available on request. ------------------------------------------------------------------------ [2007-11-26 14:08:48] marcus dot mueller at grintsch dot com I doubt this is an Apache issue since we're experiencing the same symptons as hwallenstone at gmx dot here on two debian linux boxes, one using the 64bit version of Apache's httpd 2.2.4, the other using the 32bit version of httpd 2.0.59. httpd processes seem to hang i.e. they don't close the connection (telling from /server-status) resulting in the issues mentioned above. I first noticed this behaviour when switching from PHP 5.2.3 to PHP 5.2.4, both self-compiled using the same configure options. PHP 5.2.3, unlike 5.2.4 and 5.2.5, does not expose this behaviour. I hope this info might narrow down your search path a little bit. ------------------------------------------------------------------------ [2007-11-25 14:21:58] hwallenstone at gmx dot de I think we have the same problem here. I have updated one server of a cluster of busy servers from a patched 5.2.1 to 5.2.5 . The number of apache processes is growing and as a consequence of this, the number of open files increases. We have about 50 processes running on average machines; on the 5.2.5-one the number constantly grows until it reaches my MaxClients Limit. Trying to stop apache, I get hundreds of entries like [Sun Nov 25 14:14:55 2007] [error] could not make child process 28546 exit, attempting to continue anyway This problem **definitely** has come with the upgrade from 5.2.1 to 5.2.5. Nothing else was changed. So it doesn't look like this is a old apache bug. ------------------------------------------------------------------------ [2007-11-20 09:40:33] [EMAIL PROTECTED] IIRC, this is actually an Apache bug. PHP is not the only module which suffers as 3rd party of it.. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
