Just check which process is busy from "control panel > resources > processes".
It's not showing in processes, what is using it all. I had to go to service resource occupation. In there I can see that BTRFS cleaner is what is using 100%.

Tested this numerous times. BTRFS Cleaner is definitely the problem. Doing anything on the NAS, has BTRFS Cleaner at 100%. I have disabled 'snapshot' in 'Backup'. This stopped me getting hourly CPU spikes and crashes, but the issue still remains that the BTRFS Cleaner goes to 100% and crashes TOS with any action (such as read/write).
See attached. Also, note CPU time.
