Assume that you use Microsoft SQL Server 2012 Always On Availability Groups. When you try to drop a database that's part of an availability group, you receive the expected error message 3752. After that occurs, the transaction log redo thread at the secondary may stop until you restart the database. Or, it may suspend and resume data movement for this Availability Group.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
