[JDEV] conference presence issue

[Wes Morgan]

I am running conference-v2 with jabberd 1.4.2 and I am experiencing 
strange issues with presence. When I join a room, I send the following:

<presence to="1 at classrooms.chat1.advancedacademics.com/S-Wes Morgan" 
from="9307 at chat1.advancedacademics.com/InterAActClient" id="#"></presence>

(where # is decided by JabberBeans)

If I send that to a couple different rooms, I can chat in them and 
everything works fine. But then, when I want to leave one of the rooms, 
I send this:

<presence to="1 at classrooms.chat1.advancedacademics.com/S-Wes Morgan" 
from="9307 at chat1.advancedacademics.com/InterAActClient" id="#" 
type="unavailable"></presence>

I then leave that room (as I should), but shortly thereafter, jabberd 
fires off presence type='unavailable' packets to any and all other rooms 
I'm in. I can't figure out why in the world it would be doing this. 
Another strange issue I'm having is that it ignores my custom join/leave 
notices that I've specified for the classrooms service in jabber.xml, 
which also baffles me. I can post all or part of my jabber.xml file upon 
request. Thanks in advance for any help you may offer.
