The segfaults are too regular in their timing. I'll see if the same happens at 20:08.What does your exim log say in the respective time frame?Nothing for the email in the tcpdump gets logged to any of the exim logs AFAICS.I'm not seeing any problems on this server at all other than this segfault that started yesterday at ~3am and continues every hour when the same email is retried.So it is an incoming message? Can you strace -f your exim daemon in the time frame where you expect the retry to happen?
Strace for the crashing process attached. Command was: $ sudo strace -ff -o exim_strace /usr/sbin/exim4 -bd -q30m -oX 587:465:25 -oP /var/run/exim4/exim.pid Segfault log: Mar 1 11:09:16 nakor kernel: exim4[17576]: segfault at 0000000000000000 rip 0000002a96bbb220 rsp 0000007fbfffd758 error 4
Does this also happen when you use a backport of a more recent exim version?
I'll see if I can give it a go in a little while... it's the office mail server so have to a little careful. :-)
I'll send a heads-up to the GnuTLS guys.
Not sure from the strace that that's where the problem is... but then I'm not much of an strace guru. Let me know if there's anything else I can do. I'll let you know in a while, if I can, whether the current backports.org exim (4.63-17~bpo.1) crashes.
