Hello,
We have a cluster of 4 ESXi 4.1 (U2) host.We witnessed a incident where all VM's were powered off and then were restarted by HA on two of the hosts at almost the same time,
However both the ESXi host were up during this time.
We did see some network related issues in the logs like

but since host isolation response is also set to leave VM powered so please can anyone help as to what could have caused the VM's to restart.
Thanks
