Subject Firebird is stuck when trying to open a connection after disposing a Command
Author ariel.sakin
I am connecting to a firebird database using the .NET provider.
Sometimes, when disposing an FbCommand object, I see an exception thrown inside fbembed.dll
The exception is handled, but for some reason, when I try to open a new connection to the database by calling Open() on an Fbconnection, I get stuck.
Looking at the stack shows that firebird is waiting for a lock to be released but it never happens.

Stack of the exception:
