@olivierlambert @olivierlambert said in Diagnosing frequent crashes on host: Maybe there's a usage that's slightly different since when it was "more solid" and now it's trigger more easily. Is your XCP-ng fully up to date? No; as said originally, I'm still on 8.2.1. I have been concerned about moving to 8.3 because it's a new installation, and I don't want to screw it up, but I'm willing to accept that it's the right thing to do.

@olivierlambert No, the only thing I get with xl dmesg on the host, for some time back, are random brief reports of individual CPUs running above temperature threshold and then being clocked down, and then resolving. Nothing else.
