If a client or the NetVault server has a process running that should have exited gracefully on job completion but did not we can use NVpview to kill the process as follows:
1) run %NV_HOME%/netvault/bin/nvpview
This utility displays all NetVault running processes and can trace them in real-time.
2) Kill the correct process with NVpview:
select the process from process list and press 'KILL PROCESS (SOFT)' or (HARD)'
This will kill the process
The above will allow to keep the NetVault service started and prevent you from restarting them or even rebooting.
