Also verify that for every message send (i.e., Pid ! Msg) there is somewhere
that you receive the message.  If you are using receive patterns that do not
match up, messages will accumulate that can never be removed.

You should also use a catch all message to remove any messages you were not expecting:

receive
  {From, expected_msg, Data} ->
        do_something(Data);
  AnyUnexpectedMsg ->
        log_and_skip_handling(AnyUnexpectedMsg)
end.
