[Dovecot-de] Out-of-Memory Problem mit Dovecot unter OpenBSD 5.5

[Mika]

Hi,

ich habe auf openBSD 5.5 neben Postfix auch Dovecot
installiert. Hier erfolgt die Verwaltung der User/eMail-
Adressen über eine mySQL-Datenbank.

Beim Start von dovecot bekomme ich folgende
Fehlermeldung:

# /usr/local/sbin/dovecot                 
Fatal: pool_system_realloc(8589934592): Out of memory
#

Aktuell läuft kein dovecot mehr. Der Postfix ist aber okay.

Habt Ihr eine Idee, wo der Fehler liegen kann?

Vielen Dank für Eure Ideen, Mika

P.S. Ich habe vorher schonmal dies hier machen müssen: " ulimit -n 1024"
weil da vorher die Fehlermeldung war.
