optimize Improper use? Potential bug? Your feedback is welcome:
Does the error occur when opening the database, or when you try to optimize it? In the latter case, you could tr the "optimize all" command. In the first case, it seems your data itself has got corrupt. In this case, you’ll need to create a new database, or restore an existing backup.
Please read our article on transactions to get to know more about locking problems:

Hi Easy,
I guess the problem has been fixed in the 7.8 snapshot. Could you please give it a try and report back?
Best, Christian
