[arm-allstar] If a node connects to another node, and the 2nd node later disconnects, is the 1st node or ASL notified?

[David Gleason]

I notice that if someone connects to my ASL node and I later disconnect 
them from my node, that the ASL stats pages (at least in some cases) 
then continue to show that the other node is still connected to my node 
even though it is definitely not (eg. my node might then be powered off 
for hours yet is still shown in other nodes' ASL stats pages and bubble 
charts). In terms of the IAX protocol packets exchanged between the 
nodes, when a node disconnects an inbound connection is the originating 
node notified? And is a stats update sent to ASL?  If so, why would the 
ASL stats pages continue to show a node as being connected when in fact 
it is not connected (and may have been powered off for hours or days). 
Any tips on these connect/disconnect protocol details would be much 
appreciated. Seems it would be helpful to nodes that originated a 
connection and to the ASL stats system to know when a destination node 
closed a connection so their stats would then be correct and up-to-date.

Thanks,
David
