Hallo,
hast Du Dein Problem gelöst?
Ich meine, dass sowas nur durch ein Modul / Filter passieren kann,
welches Speicher nicht freigibt - evtl. durch Segfault. Gibt es
entsprechende Meldungen im Apache-Error-Log?

Hallo,
ich habe einen httpd 2.4 dessen Hauptprozes GBweise Ram futtert und dann
irgendwann zuviel Ram verbraucht:
In diesem Fall die PID : 18154
# pstree -up | grep http
|-httpd(18154)-+-httpd(849,apache)
| |-httpd(1317,apache)
| |-httpd(1333,apache)
| |-httpd(1339,apache)
| |-httpd(1377,apache)
| |-httpd(2382,apache)
nach dem Neustart hiers ganz ok aus ( 84 MB RAM ) :
# top -c -b -n 1 | grep http

Hier war dann schluß : da hat der OOM Killer zugeschlagen.
Es gibt kein mod_php, kein mod_fastcgi in dem Apache .
Kann es sein, daß Googles SpeedPage Modul da ggf. Schuld haben kann ?
Oder ist das schon mal jemandem untergenommen?
Komischerweise tritt es bevorzugt nachts auf, wenn die Backups laufen (
IO/CPU last ).
Infos:

Server version: Apache/2.4.4 (Fedora)
Server built: May 17 2013 12:21:45
