AppVM repeatedly freezing, how to troubleshoot?

AppVM repeatedly freezing, how to troubleshoot?

I’ve tried increasing the allocated RAM and CPU, but continues to freeze.

after re-starting it I don’t see much here:

AppVM has 5000MB and 2 VCPUs allocated, locked up again today, had to qvm-kill the appvm, at the time Signal Desktop and Firefox (with 20 tabs was running, no youtube),

in the past I would never get lock ups I do have 32Gb of RAM, do I need to allocate more RAM?
is there any pros/cons to more VCPUs ? Been using Qubes for years, and hardly ever touch the “2 VCPUs” and can’t understand when one would do That…??

maybe it’s a chromium messaging extension am also using hmm

Hi @Clodius. I’ve added some formatting to your post to make it easier to read. In the future you can use markdown to format code in your posts.
