[Postfixbuch-users] Segfault bei Transport mit Cyrus

Di Dez 12 22:02:46 CET 2006

Hallo,

ich hoffe ihr könnt mir helfen. Das deliver-Tool von Cyrus-Imapd bringt
folgenden Fehler, wenn der Mailserver eine Mail empfängt:

Code:
Dec 12 21:38:54 server001 postfix/smtpd[11493]: sql auxprop plugin using
mysql engine
Dec 12 21:39:18 server001 master[11093]: process 11449 exited, status 0
Dec 12 21:39:34 server001 kernel: deliver[11505]: segfault at
0000000000000010 rip 000055555556088e rsp 00007fffc18604a0 error 4

0000000000000010 rip 000055555556088e rsp 00007fffe4800440 error 4

evtl. gehört diese Fehlermeldung von Postfix noch dazu:
Code:
Dec 12 20:55:08 server001 master[11093]: setrlimit: Unable to set file

Ich hoffe ihr könnt mir da helfen und wisst worans liegt...

Auch wär ich euch ganz dankbar wenn ihr die Config-Files mal anschaut
und mir sagt, was man da noch besser machen kann. Also der IMAP-Server
läuft soweit. Man kann sich jetzt mit username at domain.tld einloggen und
bekommt halt "keine Nachrichten" angezeigt.

Inwieweit die Postfix-Config funktioniert weiß ich nicht, da ja leider
der Transport mit deliver nicht klappt.

Wo loggt den deliver hin? bzw. wie kann ich herausfinden was die wirren
zahlen hinter segfault heißen?

Liebe Grüße und besten Dank im Voraus, Thomas
