There's really no way to know why this happens without a gdb backtrace. See http://dovecot.org/bugreport.html

# dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf

It's also possible that it has already been fixed in newer versions.

Hi Timo,

Small update on this: In 6 months the error occurred only once. The bug was not reproducible.

There was a BIOS update for IBM servers which fixes the following microcode error:

• Fixed : Intel microcode fix for a potential memory addressing error in 64-bit operating mode; it could cause page fault, data loss, data corruption or other unpredictable system behavior.

So I am assuming that it was not a Dovecot bug.

Best regards,

Morten
