Upgraded to 6.11.4 from 6.11.3.
Two crashes were observed soon after:
1) Right after upgrading, I tried to launch my WIN10VM while the dockers were loading. The system froze and my win10vm was unresponsive at login screen. All my dockers were down and my unraid GUI was unreachable.

2) During morning CA backup while my Win10VM was running. Same symptoms as before.

The consistent trend is that it crashed during docker loading I guess once on startup and once during CA backup. Both times with the VM on.
