Summary:                    Channel Group exists for nonexistent channel (didn't
clear out properly)
Description: 
A channel group was set and was expected to clear out once the channel
closed (as is the default behavior in Asterisk). The channel group,
however, did not clear after the channel closed. 

We have been unable to remove the channel manually as Asterisk does not
provide a means for this (as far as we know), since this is a feature
"managed" by Asterisk.

The channel group in question in the "Additional Information" section
below is:
SIP/2137-000001d1          2137                  (default)

I'm not sure what could be going on here, however I think we should start
with a backtrace and 'core show locks'.

Can you get that info and attach it here as a text file? Documentation for
getting that information is available here:

https://wiki.asterisk.org/wiki/display/AST/Getting+a+Backtrace

The backtrace can still be obtained while Asterisk is running by attaching
to the existing process.
