Zwave Js UI crashes HA

I have been having problems with HA completely crashing for a long time. I slowly disabled things to see what was causing it. Once I disabled Zwave JS UI I haven’t crashed in a while. I am running on a NUC with proxmox. Any ideas where I can start with trying to diagnose why I’m having this issue?
Thanks.

Insufficient memory allocated?

I think it was the firmware on my Zwave stick. I have updated it and haven’t had issues in last 2 days, will see how it goes… Thanks.
