8.0(1.78)

Description (partial)

Symptom:
The MSE (CAS) database does not have all the records in mobilestation table or mobilestation_loc table (missing data)

Conditions:
When the controllers send over 5K notifications to MSE in a short period of time, MSE may drop db update tasks from the queue for TransientCache-DBTask as the the queue limit is 5K.

This happens when MSE is started and it is synced with all the controllers.
At that time, there is a burst of notifications.
 
This condition may happen also when there is a big change in the number of clients in a very short period of time.
