Disconnected host

Hi,

I have a host which will not reconnect to vCenter. When I attempt to stop and restart hostd I receive the following error;

watchdog-hostd: PID file /var/run/vmware/watchdog-hostd.PID does not exist
watchdog-hostd: Unable to terminate watchdog: No running watchdog process for hostd
sh: cannot kill pid 2833: No such process

and of course hostd still shows as running.

I have VMs running on this host and if possible need to recover without affecting there current state

Any suggestions?

Thanks
