pfSense 22.05 showing kernel panic on Proxmox after few hours

[Snk]

Hello good day!
I would like a little help to debug what might be happening inside my proxmox VM.
The host remains stable as a rock, but the pfsense VM after a few hours, ends up crashing and restarting out of nowhere (but the VM uptime remains the same, only the pfsense uptime drops)
I have the debug file generated by pfsense, but so far I haven't been able to get any relevant information.
I've done all Proxmox updates and I'm on the latest pfsense+ version.
My VM is running with 6Gb of ram

Logs: info.0 textdump.tar.0

Also shows:

3 panics shown there in different processes.

That error usually indicates an upgrade has not completed as expected. You likely have some parts of 22.01 still present. Though I would not expect that to cause a panic.

Since it's a VM I would first try a clean install and restore your config.

@stephenw10 Hi, thanks for the feedback!
If so, would a factory reset and restore from backup be enough?
I believe it is still not possible to install directly from version 22.05, right?

[stephenw10]

Not to a VM. Not yet. However I tested the upgrade process over the weekend and it completed no problem so I would expect a clean install of 2.6 then upgrade to 22.01 and then 22.05 to work fine.
