Remove snapshot stuck for more than 20 hours - ESXi 5.0

Yesterday tried to remove VM snapshots on ESXi 5.0, and the process is stuck for more than 20 hours.
Running  vim-cmd vimsvc/task_list of this host it shows:
(ManagedObjectReference) [
   'vim.Task:haTask-44-vim.VirtualMachine.removeAllSnapshots-12580485'

The VM is unresponsive, no shutdown, does not even allow to rename the VM, any task gets an error "another task is already in progress", no problems manipulating with any other VMs.

I have no problem to lose this particular VM, but the host is in production cluster.

Thanks

this is how you should proceed:-

1. Restart Network Management Agents on the Host Server, hosting the VM.
2. Restart vCenter Server Server service on the vCenter Server.

It would appear that a Task has Hung which needs clearing.

The above functions are safe, and will not affect any of the VMs running in production.

then we can proceed with the snapshot issue, if you wish.

Looks like your, hanccocka, solution works :)
Restarted Network Management Agents on host and VCenter Service and the process gone

But now in inventory I have inaccessible virtual machine named "Unknown 37" , if I try to remove from inventory, it created another, "Unknown 38" VM
Also, I cannot delete the the old VM folder from the Datastore

Thank you

was this the VM that had the snapshot issue.

its looking likely that there is a lock on the VM, which is no surprise

there are two ways to get rid of locks, the short way restart the host, the long way, login via console or ssh, find the lock, using lsof, kill the process.
