I have disabled this function and it works fine.
My suggestion is to disable it by default, as it causes more problems than it cures.

I never had problems with VM's stopping due to no heartbeat on time and my system is really not underloaded ;)

Maybe the reason for that is that my VM's always run with priority 'below normal'.

The heartbeat is there as a protection mechanism for hanging/frozen VMs and is working well. There are a few false positives and this is something that we will investigate soon.

I got one of those on a task that was just over 12 hours run time.

(once in a while I get those over at LHC too)
