I have Windows Storage Spaces in Windows Server 2022 on a physical server set up for use in DPM using a similar procedure as here using parity for the HDDs and mirrors for the SSDs:  Add Modern Backup Storage to DPM | Microsoft Learn

It has been running this way for a while without issue. A few days ago, I noticed the DPM server performance was horrible, and the memory consumption and processor use on the system were pegged at 100% and unresponsive. The system had to be hard rebooted to get the system back up. After a short time, the same issue occurred.

I then decided to perform a clean OS and DPM install believing the issue was related to DPM. After installing the OS and before installing anything else, I attempted to bring online the imported Storage Spaces volume in the server. Everything was good until that point. After that, the memory and CPU use both continued to climb until they were both pegged making the system unusable again. It even drops RDP connections because of lack of resources. I’ve tried this same process a few times each with the same behavior. I have disabled the AV software in Windows Security and the same problem still occurs. The tasks consuming the CPU time are OS processes including a small amount by Window Error Reporting. The system has no other software installed—only Windows.

Does anyone have any ideas what could be causing this? I do not believe it is hardware related as nothing is logged in the event viewer or other areas that would indicate hardware.
