Last year I had a really weird problem with my home network. My server's network interface did not work well with my switch. For some reason, at some random time, my server was not reachable anymore. Dead. Could not ping and access over SSH.

In the IPMI Java console I did see this:

Reset adapter

You can ignore the no space left on device error, it was not part of the problem. The weirdest thing however was, that I could access the IPMI interface even though it was connected to the same switch.

I replaced the switch, network card, and cables but the problem was still present.

In order to get notified when this happens, I search for a monitoring tool and found UptimeRobot*. The free service will offer you a 5-minute interval check for up to 50 endpoints, neat.
