    [ https://issues.asterisk.org/jira/browse/ASTERISK-22678?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=210869#comment-210869 ] 

Kinsey Moore commented on ASTERISK-22678:
-----------------------------------------

This is caused by a race condition in technology switching between native RTP bridge and softmix bridge and has nothing to do with ARI at all. In this situation, the bridging tech is switched from native RTP to softmix, and then back to native RTP fast enough that the softmix private data gets destroyed before the softmix thread gets started.
