So, it happened again this afternoon. The Proxmox based server crashed. This was both a good thing, and a bad thing. Good because the monitoring script I set in place on my gateway machine worked like a charm. I got texts every 5 minutes starting at 2:10pm when the server initially went down as seen in the second image.
Bad news is…the server crashed. Well, no shit. More good news is that it did jar my memory a bit and I do recall this happening several kernel revisions ago. So for now I’ve downgraded from 2.6.32-14-pve to 2.6.32-13-pve, and we will see how stable this guy is now. I’m betting much more stable, but I won’t count my chickens just yet!
