[asterisk-bugs] [JIRA] (ASTERISK-23577) Asterisk suddenly crashes

[Matt Jordan (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-23577?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=217318#comment-217318 ] 

Matt Jordan commented on ASTERISK-23577:
----------------------------------------

Looks like an ice_worker_thread callback is occurring when the rtp instance pointer is NULL. That's a little strange; it'd be interesting to see how we managed to get the ICE worker thread started when the RTP instance isn't available.

The other option would be that the RTP instance is getting blown away and the ICE worker thread is still working.

Re-opening since there's enough information here to formulate something. If nothing else, we should probably handle the rtp instance being NULL (In which case there's nothing to do here but bail)
