Looking at syslog, trouble begins here:

Not sure what that "Resource temporarily unavailable" means - probably an out-of-memory condition.  What is that 'Verify task for disk4 started' referring to?  Maybe that is consuming all available RAM?

I just upgraded to 6.6.7, and now getting VM crashing or failing to start with the following error.

 

 internal error: process exited while connecting to monitor: sh: fork: retry: Resource temporarily unavailable qemu: pthread_create: Resource temporarily unavailable

Unfortunately still having this issue. I am trying to isolate error, but till now without success. After reboot some time cca 1 hour with issue, but then some strange lines in dmesg appears:

...

Mar 5 21:40:52 nas kernel: br1: port 1(eth1) entered blocking state
Mar 5 21:40:52 nas kernel: br1: port 1(eth1) entered forwarding state

... 

may be it is not connect with the issue, but in 6.6.1 there was nothing like that in dmesg 😞
