Summary:                    Agent shows "(In use)" and will not receive queue
calls while agent is logged in waiting for queue calls (1.4.22)
Description: 
I have a queue with approximately 50 total agents, about 20 of which will
be logged in at any given time.  Seemingly randomly (if there's a pattern,
I haven't discovered it), sometimes after an agent completes an inbound
call the agent status (as displayed in "show queue x") changes to "(In
use)" and the agent never again receives a call until that agent logs off
and logs back into the queue.  

This will happen about 15-20 times every day with seemingly random agents
at seemingly random times.  It happens when there's only one agent logged
in or when we have a full 20 logged in.  I can't identify a pattern that
would cause this problem.

This causes a huge problem, because we are missing calls and breaking our
SLA agreements with clients even though we have enough capacity and people
sitting waiting for calls.  As a workaround we are trying to get each agent
to log off the queue and log back on the queue after each call, but they
often forget.

---------------------------------------------------------------------- 
After testing the patch for two full business days, there doesn't seem to
be any noticeable change in behaviour at all.  We are still experiencing
queue agents who, after completing a queue call, will never receive another
call until they logout and login.  :-(

How do I produce a useful debug trace?  I know I have to set core debug
level to 3, but I assume that increases output to
/var/log/asterisk/messages, which is already 250MB on my machine...  Is
there a way for me to roll that log file and start fresh so that it's not
such a nasty upload for you guys?
