system crashes

[Andreas_]

In the weeks, I observe spontaneous reboots every 3 days or so. This happens on the current master of a carp router pair (slightly different hardware after repair of one router), so this doesn't seem to be hardware related but appears caused by some kernel update in the last months.
The system.log doesn't help, it just logs the fresh boot. External monitoring doesn't show any anormal traffic or load (0.5 load, 2-5% CPU) on the Atom C3758 system with 19.1.9.

Any hints how to narrow this down?

I am facing an even worse situation when the system crashes but it does not reboot and I do have an i7 based system.

Some issue: clog /var/log/system shows nothing interesting before the crash and the RRD database content seems to be missing all the data since the last reboot (almost one day).

I tried to look for an option related to how often the database is dumped but I was not able to find one.

At least I am lucky that my router does crash only every other week, and is clearly not getting out of disk or RAM (8GB), cpu load >10%, temperature ~55 celsius stable.

Did you try reverting the Kernel?
