Since the upgrade from 2.0.5 to 3.0.2 we are no longer able to perform a dropAll on one of our schemes. Besides this the dropAll takes about 15 minutes now (compared to 30 seconds with version 2.0.5).
It takes a lot of time because a lot of following SELECT statements are executed and each takes about 15s to complete (although the resultset in general is empty):
In the end it fails because of following exception:
The dropAll of the same schema still works if we try with version 2.0.5 afterwards.
The update works fast and fine.
