I have a rig that is crashing every 3 to 4 hours and I cannot pinpoint the reason why.
The crash affects somehow the ethernet interface (or maybe the TCP/IP stack), and the rig becomes unreachable by ssh and doesn't respond to pings.
It basically needs to be reset manually. This is quite annoying as I live several hours away from where I have the rigs.

Is there a way on how to investigate the crash and how to find a solution?
