asterisk users - Aug 2007 - Members in 'Unknown' status in output of 'queue show'

Does anyone know what can cause queue members to go into a status of
"Unknown"?

pbxtel-01*CLI> queue show

cs        has 2 calls (max unlimited) in 'rrmemory' strategy (24s
holdtime),
W:0, C:447, A:20, SL:91.7% within 60s

   Callers:
      1. Zap/50-1 (wait: 11:15, prio: 0)
      2. Zap/36-1 (wait: 0:41, prio: 0)

That's just one queue, but I had nearly all my agents just go into Unknown
status.  This is on * 1.4.10.1.  I had this happen once in the past, but
couldn't reproduce it in the lab.

When this happens, 'ringinuse=no' stops working, because app_queue
considers
"Unknown" to be a valid state to dispatch a caller to.  So my agents
start
getting flooded with calls while already on the phone, then the call-limit
I've configured in sip.conf kicks in and my console fills up with this:

pbxtel-01*CLI>

I had to restart Asterisk to clear the states - sip reloads, app_queue
reloads didn't do anything.

Any thoughts as to where to start debugging this?  I killed * instead of
stopping it so that I got a core file.  There is nothing in the log to
indicate what went wrong prior to the first instance of "...rejected due to
usage limit".

Anything else I should gather before submitting a bug?

Thanks

 I think we will want to see what state chan_sip is sending into
app_queue for it to be called "Uknown". What is the last state these
channels are in before they go to "Unknown" in app_queue?
