Yes. Either remove them for yourself or get the master branch,
and recompile, then overwrite the piler-smtp binary.

Hello,

thank you for both of your feedbacks. As much as I dislike systemd,
it allows you to restart piler-smtp in case it crashes. But hopefully
it won't happen in the future after this fix.

Also I've merged it to the master branch, and I'll release a bugfix
version 1.3.11, and I'll make a deb package.

Janos, Patrick,

thanks for this. I also run piler on Ubuntu 18.04 and ran into thesame issue.

My 'solution' was to start piler-smtp automatically via monitoring if
it goes down :-(.

Janos, I wonder if you will provide updated .deb packages fordpkg-installs?


Thanks and regards,
Claudio

Thanks Janos,

I'd updated and replaced the piler-smtp binary on 2021-02-16, and
while I can see that my monitoring still shows SMTP timeouts on the
piler port sometimes between 02:30 and 02:40, no further outright
crashes / SIGSEGV occur, so archiving continues without any need to
restart the process manually.

Hello Patrick,

thank you for your feedback. I'd like you to update the smtpsegv

branch, and recompile piler-smtp. I've refactored the timeoutchecks,

and pushed the commit to the branch on bitbucket.

Hello Janos,


happened Sa->So this time.

Logs (piler-smtp as compiled out of smtpsegv.tar.gz source code)see

below, SIGSEGV follows right after free(session) done.

It is also interesting to see that the piler daemon finishes
processing a message 2 whole minutes after the smtp process has
already segfaulted and and stopped supplying any new messages.


Thanks, Patrick
