Can high memory usage cause Proxmox to reboot on its own

[Edmund Fiadzo]

Hello Support,

We have a Proxmox cluster with no high availability resource in place.
We would like to know if high memory usage ( above 90% mem usage ) among one of the cluster nodes can cause it to automatically reboot on its own?
We have noticed these reboots and we are not able to tell what is causing it .
Kindly give us some guidance to aid us investigate this issues.

Best Regards

do the host have swap configured?
when yes. how is the usage?

without HA active there shouldn't be an intentional shutdown/reboot. but it is of course possible for a server to crash for whatever reason. if the logs don't give any indication, setup netconsole or a serial console and try to catch any errors that way.

There is swap configured, and its usage is also very high too most times.
