[Openais] Re: FW: Evt Deadlock

[Muni Bajpai]

So I think the basic premise of what I saw was that In the HandlePut
call, the thread in question was holding the channel_handle_db lock and
requesting the event_handle_db lock. So for deadlock to happen another
thread has to hold at least the event_handle_db lock and requesting the
channel_handle_db lock. 

I'm not sure if any path in make_event can fulfill the above criteria
(0.70 code) to cause a lock but then again I might be missing something

Thanks

Muni

OK, I found a bad bug.  I don't know if it is related to anyones
trouble, but it is bad.  In make_event (creates an event structure in
the library code) the new event is destroyed if there are any errors.  I
was using the wrong handle database to destroy the event handle.  Here
is the patch.  This will need to be checked into the picacho branch too.
I'll create a bugzilla entry too.

Mark.
