Prozesse werden beendet

Hallo,

in Unregelmäßigen Abständen werden Prozesse beendet.

Zufällig.

Meistens habe ich in der Log stehen z.B.
fork() failed: Cannot allocate memory


Aber es steht zu 100% genug Ram zu Verfügung.

Es handelt sich um Debian 6 und um ein Mailserver.

Danke im Voraus

Dann wissen wir ein wenig mehr (vermute mal es handelt sich um eine OpenVZ Büchse)

Welche Daemons kommen für den Mailserverbetrieb zum Einsatz?
 
Jup ist OpenVZ. Habe auch Zugriff auf den HyperVisor

Daemons: Postfix mit Dovecot als Mysql
 
Schau dir doch bitte mal folgende Werte an:

kmemsize und numothersock

Möglicherweise wäre es sinnvoll wenn du deren Soft und Hard Werte überarbeitest, der failcnt sagt jedenfalls schon einiges...
