[asterisk-bugs] [JIRA] (ASTERISK-25279) Deadlock using chan_sip

[Dmitriy Serov (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-25279?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=227153#comment-227153 ] 

Dmitriy Serov commented on ASTERISK-25279:
------------------------------------------

I used all versions starting with 13.1. Updated with git "between" versions. 
Of course, something changed, but in version 13.1, 13.2 and, not too sure, 13.3 I don't remember such problems.
On all latest versions of branch 11 of the server with the same settings (except for the lack of pjsip) worked for months without problems.

Strictly speaking it is incorrect to name "the deadlocks" the situation in these backtraces. Watchdog ensures a strong excess queue, essentially to stop processing packets for clients.
