    [ https://issues.asterisk.org/jira/browse/ASTERISK-26832?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=241354#comment-241354 ] 

Jan Rozhon commented on ASTERISK-26832:
---------------------------------------

In my case, all crashes appear during sending 183 Session Progress messages. I have like 10 backtraces all pointing to a crash caused by this message. So I configured my edge asterisk boxes (all on 13.13-cert branch experiencing no issue of this kind) to filter the message and send 180 ringing instead. Since I did that like 6 weeks ago, I have had no crash of my central (experiencing problems) box because of this bug.

Hope this helps narrow down the possible causes.
