You need a procedure to cleanly shutdown the Detection servers.

1. To start or stop a Symantec DLP server: 
2. Go to System > Servers and Detectors > Overview.  
3. Click on the desired server. The Server Detail screen appears.
   • If you have enabled Advanced Process Control, DLP displays general server status as well as the statuses of the individual processes.
   • If Advanced Process Control is not enabled, DLP displays general server status only.
4. Do one of the following:
   • To stop a server or a process, click the stop link in the appropriate field.
   • To restart all server processes, click the recycle link. (This option is only available for detection servers.)
   • To start a server or process, click the start link in the appropriate field.
   • To track the status of the server(s) or process(es), click to refresh the screen.
5. When the server reaches the expected state, click Done.
