tinc - Feb 2019 - Tinc node is crashing after some days or weeks. How to debug?

Hi
Im running tinc 1.1pre17. My problem is that my tinc nodes occasionally crashes.
When it crashes the tinc node is not running anymore. Time between failure can
be sometimes days or weeks.

Do anyone here have a proposal for how to debug and get this problem solved?


Best regards,
Håvard Rabbe

I assume it doesn't produce anything in the log?

Try strace?

Though be aware it will slow down tinc, and produce a lot of output 
(please redirect the output to a file / choose file logging).

A coredump would be more interesting and wouldn't affect performance. If 
you're running tinc from systemd, you can install systemd-coredump.
