Resolution

Here is a procedure to clean up DMS/DH

2. Unsubcriber the message queue from DMS__ first. 
3. Please purge all the message in message queue. 
4. Please remove DH__.status in all DS. 
5. Please remove DMS__ status and updates.dat and all subscribers files. 
6. Please double check no pending message in message queue. 
7. Start up DMS__, 
8. check if updates.dat is growing fast. 
9. Ideally, we want updates.dat to be zero byte. 
10. Add the message queue back to DMS__'s subscriber's list.

11. Message is sending to the subscriber's message queue.
