I just started to see strange behaviour in which our server seems to
kill itself without no apparent reason.
Logs:

It seems that 00:01:41.540 watchdog process has decided to stop the
resin. I don't know why as no-one was online on the machine on that
time.
Any help or thoughts how to debug what could be going on?
