I'm not sure I completely understand what you say above but it sounds a bit like
you may be having two processes trying to get write access to a single acedb
database at the same time. Unfortunately you cannot do this, only one process
can have direct (i.e. not via the acedb server) write access at a time.

Can you check whether this is the case.
