For a while, the windows machine I was using kept randomly becoming unresponsive (both via network, as well as the keyboard+mouse) and I just could not figure out why. Everytime it did, I’d have to force a shutdown by holding the power button until it shutoff, then press it again to start back up. Sometimes this happened while I wasn’t home, so it had to just stay offline until I was.

I got sick of having to do this; so I replaced the power button with a transistor and a RPI. The PI would ping the server every 5min; if it failed to get a response 3 times in a row, it would trigger the transistor for 10sec, release for 3sec, then press and release again; forcing a poweroff then starting the machine again. It’d also write these events to a log file. I think it was around twice a week ish.

Never did figure out what the cause of the lockup was; but it stopped when I replaced windows with Debian.

I have a NAS that had a similar problem, every week or two it would stop responding. From the logs it was clear that the machine was running fine after going non-responsive, but either the NIC or something else network related was crashing. However, the logs weren’t capturing the exact issue. I wrote a script to ping Google every 10 minutes, write a bunch of debug data to disc if it failed, and then reboot.

And it has never happened in the year since. I have no idea what the root cause was, but sending those pings out seems to have fixed it.
