HI Guys,

My Proxmox is freezing and need a reboot every 4 / 5 hours, even with low cpu load.

What i've tried so far:
- Switched the NVME's (they are in raid1 2x 2TB, also tried without raid, same issue)
- Switched the RAM modules
- Reinstalled proxmox with 7.4
- Reinstalled proxmox with 8.0
- Memtest complete without any issues

ksm_scan_thread might indicate KSM. You can try disabling it. If might also indicate a memory corruption (run memtest for a long time?) or other faulty hardware.

Today it crashed again with different errors underneath <TASK>

It was stable for 80+ days before i added the following hardware:

2x G.Skill Aegis F4-2666C19S-16GIS
2x Corsair MP600 NH 2TB (NVME)
2x Seagate Exos X20 - 20 TB
1x PNY Nvidia Quadro P2000

Before:
2x Samsung EVO 970 SSD's
4x Seagate Exos X20 - 20 TB
2x G.Skill Aegis F4-2666C19S-16GIS

After:
2x Corsair MP600 NH 2TB
6x Seagate Exos X20 - 20 TB
4x G.Skill Aegis F4-2666C19S-16GIS
1x PNY Nvidia Quadro P2000

Memtest is running, first test passed after a hour with 0 issues, how many runs do you suggest? And if you see the list above can you point out which can trigger the errors?

I got a 4-port Quadro in my workstation. The benefit I have of four screens hardly outweighs the amount X-restarts, Plasma freezes and kernel crashes. It's my first nVidia card in years, having stayed with manufacturers that do provide proper open source drivers. I had not imagined the state to be so bad.

Your nVidia would be my first suspect!
 
In my case the freezes are happening on Intel NUC with UHD gfx though :D
 
Have you ever resolved the freezes?

The problem was a faulty RAM module, unless MEMtest didn't showed any issues after replacing the RAM modules the problem resolved. :)

This! I had this exact experience once with a piece of ... hardware ... too. :D
