[asterisk-bugs] [JIRA] (ASTERISK-30070) pjsip: assertion and warnings with webrtc

[Joshua C. Colp (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-30070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=259200#comment-259200 ] 

Joshua C. Colp commented on ASTERISK-30070:
-------------------------------------------

Generally you can tell if a deadlock is happening... for example if you hang up and the channel is still there, that's usually a deadlock. DEBUG_THREADS heavily influences the timing of things and effectively single threads the system, which is why I'm asking for testing without it. If it's fine without it, then that alters the scope and impact of this issue because in production you wouldn't use those options.
