I've had so many issues on 6.11.x. edit: I admit, I skipped all of 6.10, so the issues may have started there. I can test that if necessary.
I thought they were hardware problems at first. Ran memtest on each of my 4 modules, all passed.
Bought a new NVME drive, since I was seeing some odd errors, rebuilt cache pool completely, still have issues.
Moved one NVME drive to an external enclosure over USB-C, rebuilt btrfs since the drive "changed," still have issues.
Rebuilt docker.img since it had a back block (or something?) that scrubbing couldn't fix. Still have issues.
My unassigned USB 3.0 RAID0 drive that I access over SMB has had performance dropping to 0KB/s, and doesn't work at all now.
SMB in general has been crashing and fails to mount on my Windows machine.
Randomly, after a few hours (or even minutes at times), Unraid just crawls to a halt and the web interface is unresponsive.
I'm reverting to 6.9.2 which is my oldest flash backup now, will report back if I have the same

edit2:
Back on 6.9.2, no errors in my log unlike 6.11. SMB speeds for a mounted vhdx on my USB drive array are back to normal, 2.5Gbps+.
Over two hours now, no errors in my log. This is a new record lately.. Something doesn't like my hardware on the newer versions.
