we have a situation where by virtual images have rebooted randomly . disabling HA seem to have cured the problem,but i really need HA re-activating
We are still on a 3.5update2 platform and have been using the some configuration for months with no issues??
Disable VM heartbeat monitoring in HA settings.

i thought about as this was an issue with update3, hence why we have stayed on 3.5 update2 ..But we dont have this enabled..
Then you should check which VMs rebooting, are they on a particular ESX, or is this a cluster-level issue.
I know only one cluster-level HA issue with VMs - VM monitoring.

looks like its tied to the fact that vmkping is not woring on the cluster in question !!!
