VM are stopping sometimes and can't be restarted

[Marco Ertel]

Hi,
I am running the actual FN11-U4 (details see below). Sometimes in the middle of the night (also tonight) all VMs (I have 4 with Ubuntu running) are stopped but this is not reflected in the UI and it is not possible to stop (and start afterwards) them from the UI. I only can force to stop them with the commandline (bhyvectl --vm-name=... --force-poweroff) but can't restart them without completely restarting freenas.
Has anybody else already seen such a behavior?
Where can I start to search (some log files or something like that)?

Thanks and Kind Regards,
Marco

YES I've seen this behaviour. I sometimes have to stop them by

Code:

ps -auxw | grep vmname
kill -9

I'm pretty sure it has to do with networking.
