Recently installed VM and started running QuChemPedIA@home. Finally finished a few WU's but keep getting "Postponed: VM enviroment needed to be cleaned."
Running on 8 core AMD FX-81120 with 16GB mem and 120GB SSD.
Am I missing something or need some adjustment? or is this normal?

You shouldn't be seeing that message, there's some kind of a problem. What version of VirtualBox are you running?

VM verion 6.1.12
I've tried several online suggestions and seen talk about going back to an older version. But those were old forums.
Set switch between tasks and checkpoints very high. Set most CPU time to 90%, now trying 75%.
Also reporting VM job unmanageable restarting later.
Must suspend and restart BOINC client from task manager.
Running with WUProp, plus Milkyway on single GPU. QuChem is running on 6 of 8 cores.
CPU and memory usage is low. Temps good.

One online suggestion was setting "use at most 75% of CPU time".
Tried 90% = fail - Tried 75% = good - Tried 80% =fail
Running good all day at 75%, but still don't know why. :unsure:

VMs always run at normal priority and the tasks that need to manage the VMs run at low priority (by default). This can lead to the management tasks not getting enough CPU time.
