This database doesn't have any create / drop table
Weird. You shouldn't be seeing severe GAM contention in a user DB... If it happens again, can you capture the queries that are involved? It may shed some light on what's happening and why.
Are you doing lots of data loads in parallel? (multiple sessions all inserting large quantities of data)
