appvm crashing whole computer?

[Stumpy]

My computer started freezing up recently and I had origonally thought
(as it is pretty old) that it was dying. I then realized that it *seems*
to be an appvm, or something within this appvm that is crashing the
computer as, so far, the computer has not crashed if i dont have the
appvm open.

My question(s) are, I thought appvms or apps in them where "contained"
so couldnt crash a whole system? and, are there some logs that can help
figure out what is happening?

Thanks!

It is possible that running a resource-intensive process inside of an
app qube could cause an old or poorly-ventilated computer to crash. (For
example, it's common for dust to accumulate on CPU heat sinks after
years of operation, causing thermal limits to be reached even under
normal workloads.) If this is the case, everything could still be
properly "contained" from a security perspective and nothing malicious
need be afoot. It could just be that the underlying hardware is failing
under load, which often manifests as spontaneous hard reboots.

This is just one possibility to consider.

Thanks.
If a cpu intensive task can do that then that might be the problem. My
setup is old, but i keep it pretty clean so dust/overheating seems less
likely. It is my "multimedia" appvm that I have sshfs'd to a network
drive playing music on a win app via wine, which doesnt seem super
intensive but xentop tells me otherwise. The thing is, I have had this
setup for years and it hasnt been a problem until now?
