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 
           or other unpredictable system behavior.

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

Best regards,
