When you stop the FRM all transactions which are in the process of
committing will be rolled forward, it is committed. When a transaction
fails while in the commit phase it will not be marked as failed, but
will be available for commit later. Maybe this is a bit odd and should
be changed?!

The stacktrace would really be important. When the error occurs while
commit and not when you synchronize commit it is most likely that two
commits clash in a way they should not.

By the way synchronizing the commit takes a lot of possible
concurrency from the manager as at most one tx can commit at it time
in this case.
