Description (partial)

Caveats if DB VACUUM process takes more time (~ 5 mins)

Symptom:
* Few of the WAEs might go offline. But this is temporary, once VACUUM process is complete, they will be online automatically.

* Statistics Aggregation threads might take more than 5 mins and the same would be indicated in the logs. As a result, 1 or 2 (based on amount of time taken for DB VACUUM) statistics samples will be missing at Network level.

* User including admin will not be able to use (login) WCM as the complete DB will be locked.

* Below exceptions will be seen in cms logs.
