Hi Tony,
I’ve seen this issue when you are running overpopulated compute nodes are run out of memory. Are you oversubscribing memory by any chance?
Thanks, Mohammed

For some reason today morning VMs on one of my compute Nodes started shutting down themselves.
When I checked in Horizon, I realized that that particular Compute was disabled and I enabled it. I restarted the Instances and all is well now.
I have attached the Logs for nova-compute in case someone would like to help.
