Bug#399776: apache2: Apache 2.2 spawns lots of processes and freeze the box
Hi, I suspect this might be a php bug. Is there anyone who can reproduce this bug who does _not_ use php5? Thanks for your help. Cheers, Stefan -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

There are reports about memory leaks in mod_python (with more than one handler): http://issues.apache.org/jira/browse/MODPYTHON-181?page=all and mod_proxy: http://www.modsecurity.org/blog/archives/2006/08/apache_reverse.html Try whether MaxRequestsPerChild, MaxKeepAliveRequests, etc. help. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

The are no errors or other interesting entries in apache logs nor in any other log. The box has 1Gb of RAM and 3Gb of swap. I know that 150 processes can use up all memory and that's why we reduced the max clients to 25 but the real problem here is that Apache 2.0.53 run for about 1 year with the exact same configuration without any problem. The problems started the day after the upgrade to 2.2. What was strange was the high number of defunct apache2 processes. I'd expect to find something about them in apache error.log but no, nothing was there. federico -- Federico Di Gregorio http://people.initd.org/fog Debian GNU/Linux Developer[EMAIL PROTECTED] INIT.D Developer [EMAIL PROTECTED] Best friends are often failed lovers. -- Me signature.asc Description: Questa è una parte del messaggio firmata digitalmente
Bug#399776: apache2: Apache 2.2 spawns lots of processes and freeze the box
Some questions: - are there any interesting entries in the apache error log? - anything interesting in syslog, kern.log, ...? - are you using php/cgi/... or just static content? If you use php, what memory_limit have you set? - what other modules do you use that are not enabled by default? - how much memory+swap does your box have? How much of this is used by other processes? If your Apache does something quite memory consuming, 150 processes are quite a lot (and maxclients 150 means that you can have up to 150 processes). Maybe you are just running out of memory and the oom-killer goes berzerk (as it usually does). Cheers, Stefan -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
