Docker makes my omv4 install very unstable.

Docker, for whatever reason makes my omv 4 very unstable. When the cpu gets high, it crashes cores. I saw this a lot with plex and insync and pihole.... anything that creates high cpu in docker. On latest kernel avail on extras. Tired pv kernel and half of my nfs shares disappeared. I tried to install later kernel with ukuu and just would not work. This used to be a Ubuntu 18.04 server that would go months without reboot and issues. I have now uninstalled docker and installed plex and pihole outside of omv in os directly and very stable again. This is a AMD A8 on arock motherboard with hightpoint raid card. 3x velicioraptors in raid 5 and 16x4TB sata drives in raid 6 (44TB).

What is docker doing that is crashing my server?

locks up and i cannot ssh or log into console. The raid card has been supported since linux 2.6.x... However, now it has been stable for 18 hours... would not go 2 hours before. At first i thought it was the kernel... but with docker uninstalled, it has been stable.

update... has not crashed once. What is docker doing that makes it so unstable? I have installed everything the conventional way (not my preferred way).
