In a multi process setup, I've noticed if you stop the agent but keep 
Tomcat going, you most like will hit a key violation error like the one 
below.  I remember reading they don't have to be both restarted, but 
what if they do?  What if I need to issue a LockClean in between?

Error: ERROR: duplicate key value violates unique constraint
