SIGABRT on fetching mail

[Peter Nabbefeld]

Hello,

I'm running dovecot with getmail for several months already, but today
it's always crashing: "getmailrc: operation error (child pid 2995 killed
by signal 6)".

The deliver process aborts due to an unknown reason.

How can I find out which message is causing the crash?

It would be very helpful, if the message's subject and receipt time
could be logged in case of an abort or anything else that could help
identify the corrupt message. This would also enable me to send You the
message for further investigation (if appropriate).

Kind regards
Peter
