    [ https://issues.asterisk.org/jira/browse/ASTERISK-27338?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=239326#comment-239326 ] 

Richard Mudgett commented on ASTERISK-27338:
--------------------------------------------

The backtrace isn't too helpful because it shows the ao2 object has to be a format and formats are referenced in a lot of places.  Certain formats like slin, ulaw, and alaw can get a lot of references normally.  I imagine the ao2 object that reached the excessive ref count is the slin format since the code was trying to write a frame toward a softmix bridge channel after mixing audio.

About how many channels did you have in confbridge/softmix bridges at the time?
Do many normal calls on the system have to do format translations?
How is the system used?
