Janos, Patrick,

thanks for this. I also run piler on Ubuntu 18.04 and ran into the same 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 for dpkg-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.
