[Asterisk-Users] Agent channels causing problems

[Julian Lyndon-Smith]

CVS HEAD as of two days ago.

We have 50 agents (All SIP, with inbound/outbound via ISDN32 using a 
TE405P with revision 2 firmware), logging in via agentcallback. At the 
start of every day I restart * (service restart) At the end of today 
(and most other days) we have the following problems:

foxtrot*CLI> show channels

9 active channels
4 active calls

Everyone has gone home, there are no active phone calls. I cannot 
destroy these channels by issuing a hangup - it just gets ignored. Queue 
calls to these agents do not get through, yet a direct dial (i.e. call 
the extension works just fine).

I'm posting this now because I have a window - everyone's gone home, but 
the * server is still running. Is there any diagnostics I can run, gdb 
or anything like this to try and get a handle on what is happening here ?.

Any help ? Please !
