Recurring crashes on VM
-
I'm not sure if this is specifically an XCP-ng issue, so forgive me if this isn't the right place for it. I'm also not sure what details would be most useful to share, but I can describe my setup further as necessary.
I've been running XCP-ng for a few weeks, and for the most part everything has been going well. I have about 6 VMs running, all based on vanilla installs of Debian Bookworm. One of these VMs serves as a Docker host, without about a dozen containers running in it; this VM has more memory and CPUs dedicated to it than others, but still runs comfortably (i.e. it's not always at 100% CPU or running out of memory or anything). Every couple of days, this VM has crashed; this doesn't appear to be associated with anything that's actively happening (i.e. it doesn't seem to happen when I do something specific on a container, it just happens). I'm attaching the dmesg output of a crash, but it starts with a "general protection fault".
What can I do to figure out what's going on?
Thank you.

Can you check on the host with
xl dmesgif you can correlate? -

No, the only thing I get withxl dmesgon 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. -
