[Postfixbuch-users] Merkwürdige Fehlermeldung: "insufficient memory"

[Rustedt, Florian]

Hallo zusammen,

Bei einem MX-Relay mit 8 CPUs und 1G RAM bekomme ich dauernd folgende Meldung:

[2009 Mar 14 07:22:43] mx1 crit: postfix/qmgr - postfix/qmgr[2306]: fatal: myrealloc: insufficient memory: Cannot allocate memory
[2009 Mar 14 07:22:44] mx1 warning: postfix/master - postfix/master[3778]: warning: process /usr/lib/postfix/qmgr pid 2306 exit status 1
[2009 Mar 14 07:22:44] mx1 warning: postfix/master - postfix/master[3778]: warning: /usr/lib/postfix/qmgr: bad command startup -- throttling

Schlimmer ist noch, das allem Anschein nach E-Mails verloren gehen, ich vermute mal, dass die in den "gestorbenen" qmgr-Prozessen verlustig gehen....!

Natürlich hat das System in dem Moment immer genug RAM frei, Festplatte hat auch keinen Engpass..

Hat mir da jemand den entscheidenden Hint?
Die master.cf ist unangetastet wie von p'fix.org, unten noch die main.cf.

Gruß, Florian
