I'm not 100% sure if 15890 is related, but I'm marking it as such for now as they appear similar.

Is this still an issue with the 1.6.2 branch (see below).
Per the Asterisk maintenance timeline page at http://www.asterisk.org/asterisk-versions maintenance (bug) support for the 1.6.0 and 1.6.1 branches has ended. For continued maintenance support please move to the 1.6.2 branch.

More information on this change can be found in the release announcement: http://www.asterisk.org/node/49924

I believe this is related to ASTERISK-23373.  The channel/RTP leaks should be resolved by this.  Is the REINVITE issue resolved?  Note 1.6 is out of support, so you need to be running, 11.8.1, 12.1.1 or higher.

I'm going to go with Corey on this. If it turns out I was wrong, please feel free to comment here (whoever) and we'll reopen the issue.
