SIGABRT on fetching mail

[Peter Nabbefeld via dovecot]

Good Morning,

I tried using gdb, but that doesn't work for me:

$ ulimit -c unlimited
$ sudo systemctl restart dovecot
$ sudo -E getmail
getmail version 5.13

Finally, I could find a file in /var/lib/systemd/coredump:
-rw-r-+ 1 root root 710416 30. Mai 08:54
core.deliver.1003.d14b28050b8343f5a60c5998ef3947df.19702.155919928600.lz4

This is obviously the required dump. However, I'd not attach such a file
to a post to the mailing list, so where can I put that? Send it directly
to You?

Kind regards

Peter

PS: I'm using Arch Linux - probably the hint above could be added to
https://www.dovecot.org/bugreport-mail as a hint for other Arch users,
as it's much easier than using gdb for those not using it?

Maybe this helps?

SIGABRT on fetching mail

[Peter Nabbefeld via dovecot]

Hello,

I've never used gdb, so I don't know why I'm running into problems using
"gdb bt".

Usually, I'm fetching my mail using "sudo -E getmail", but this doesn't
seem to work with backtrace. :-/

Output from "dovecot -n" attached.

Kind regards,
Peter

Hello,

thank You for Your reply!

If I knew, which message caused the problem, I'd probably just removed it.

I'll send the dovecot version output later, when I've found out how to get the 
gdb output - don't want to fragment this thread more than necessary.

Kind regards,
Peter

Hi!

I read your previous email, can you provide gdb bt full from the core file? 
Also, doveconf -n and message corpus (if possible) would be nice to have. If 
you need to, you can try 

https://dovecot.org/tools/maildir-obfuscate.pl

to obfuscate the mail beforehand.

Hello,

I still cannot fetch my mails, relying on my smartphone (which makes it
a burden to read my mails ...) - could probably somebody help me?

SIGABRT on fetching mail

[Peter Nabbefeld via dovecot]

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
