[erlang-questions] Can't shut down Mnesia from within application

[Lukas Larsson]

Mnesia:stop sends a call message to the application process to stop. That
process is busy shutting down your application and thus a deadlock happens.

console and it will immediately shut down as if nothing is wrong. The
freezing up only happens when I try to call mnesia:stop() (or
application:stop(mnesia)) from within the applications stop function.

In the stop function of the same application I call mnesia:stop(). At that
point I shouldn't have any transactions or anything going on, but Mnesia
simply hangs and I can't do anything but shut the Erlang VM down and restart
it again. Any ideas what might be going on or where I should look?
