[cisco-voip] CUCM Location question

[Ryan Ratliff]

There are quite a few call leak bugs out there.

A cdcc is what ccm uses to track a call.  Every call ever made gets  
one, and if they aren't cleaned up properly represent an actual  
memory leak (though a small one).  Enough of these leaked can cause  
big problems if it goes on long enough.

In order to find out the specific bug you are hitting you will need  
to get CCM and SDL traces covering a time period where there was  
known to be no leak, through when you know a leak occurred.   
Typically you check the perfmon counters one night when you know  
nobody is on the phone and make sure Active Calls is at 0.  The next  
night if it's gone up and you again know nobody is on the call, grab  
the traces from the last 24 hours and open up a TAC SR.  We have  
scripts that we can use to identify the specific cdcc(s) that leaked  
and from that we can zero in to find out why it leaked.

Ok, it appears to have a bandwidth leak. A reboot has cleared the
issue and the bandwidth values in RTMT are good a day later.  What
does cdcc stand for?  I'm searching bug toolkit for bugs. This is on a
5.1.1-3126-1 version cucm BTW.

Thanks.
