Subject: [Sysadmins] падения апача под нагрузкой
Date: Wed, 23 Dec 2009 19:41:41 +0300
Message-ID: <4B324845.9060302@altlinux.ru> (raw)

С недавнего времени стал падать апач. В лог ругается

getent passwd | grep 111
syslogd:x:105:111::/dev/null:/dev/null
apache2:x:111:118:Apache2 WWW server:/var/www/apache2:/dev/null


Думал что возможно не хватает numproc -  увеличил значение до:

apache2  soft    nproc  8192
apache2  hard    nproc  8192

не помогло. Во что ещё может упираться?
В open files ?   (1024)
