Hey everybody. I found this interesting. It’s likely not a game changer for anyone, but “hardware” watchdogs in Proxmox was a new one for me, and was a cheap and easy, hacky fix to deal with a low value VM that was periodically hanging. This is a nice tool to add to the belt, hope you all enjoy!
This won’t help my old ass mFi/mongodb VM but it looks very useful for other shit. Ty!
Nice.
Other actions are possible with watchdog timers, especially with hypervisors. They can invoke a script or use an agent to kill a misbehaving process.
Ultimately, the best solution is not to need the timers at all, so finding the culprit within the client is ideal, though not always possible.
VMs hanging on memory often have incorrect caching policies, you may want to investigate that.
