Killing a defunct vpx-agent process in VMware ESX Server 3.5.0 build-64607

I am trying to reinstall VirtualCenter Agent in this ESX Host. When I try to start the vmware-vpxa service in the host, I get the error which I have updated below

The ps -aef commands shows this

The ESX Host is running Virtual Machines that are very critical.

Please provide a method to restart the vmware-vpxa service without restarting the Host.

Ok. Looks like a reboot is the only option then.
I know you mention there are critical VM's on this host, but why can't you shutdown the VM's and reboot the server during non-operational hours - there has to be at least 10 minutes in the day when this can be done? I know all your VM's are hosted directly on the server, but if the VC functionality is getting to you then this may be your only option. Also looks like it would be a good time to update your ESX 3.5 since it running Update 1/2, I think. Just my humble opinion.

Use the PID returned from your ps command to then run this command
 kill -9 PID
where -9 mean kill with extreme prejudice  (don't know I feel about that though ;-) )

za_mkh,

I have already tried it, it does not kill the process.

I will try to schedule a downtime for the same and will update you accordingly.

Unfortunately, the Host cannot be restarted since the VMs are mission critical.
