This is probably related to another ticket I have open ASTERISK-17290
I am attaching debug logs from that ticket here also.

Over on bug report ASTERISK-17263 jpeeler has uploaded a patch bug18637.patch which gets rid of the zombie channels but adds a lot of locking and unlocking.
Based on that patch ASTERISK-17291 could probably be closed out because these zombies disappear with bug18637.patch

This issue is fixed in r306120 so this report can be closed out.
