Summary: 'Unknown' member status in app_queue
Description:
Without any obvious trigger, a large number of the members in all of my
queues changed to a status of 'Unknown':
cs_billing has 11 calls (max unlimited) in 'rrmemory' strategy (114s
holdtime), W:0, C:1771, A:58, SL:93.8% within 60s

This has happened once before (when we were running 1.4.9) just over a
month ago. I was unable to reproduce the behaviour in a lab environment.
When this happens, ringinuse=no stops being effective (because 'Unknown'
members are considered available to take a call. app_queue starts to
dequeue calls to agents who are already on a call. The SIP channels of the
agents have a call-limit of 2, so when this happens the log fills up with:

Attempts to have remove and add agents does not fix things - they go back
into an Unknown state as soon as they have completed a call.
The only way I could resolve the issue was to restart Asterisk. I killed
the running process to generate a core file, which is attached. The
tarball also contains a full backtrace and a copy of the asterisk binary,
which is from a 'Linux pbxtel-01.comwave 2.6.9-55.ELsmp

14:04:42 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux' system running CentOS
4.5.
There is nothing obvious in the logs preceeding the trouble to indicate
why agents were marked as 'Unknown'.

I just asked for a status update on this one, since it appears that this is
a chan_sip issue. It appears that this is not resolved yet.
