Diagnosis
If all the requests are activated, the U table of the DataStore objectsis deleted by a truncate table.
This only happens if there is no new loading job running in theDataStore object or if there are old requests in the DataStore objectthat have not yet been activated.

System Response
The system was unable to delete the update table because it could notset a lock on DataStore object &V1& due to the fact that another lockhad already been set.

Procedure
The next time requests are activated in the DataStore object the systemwill attempt to delete the U table. The worst case scenario is thataccess will be slower than usual during activation and more space on thememory will be wasted.
