> Presence Causes Deadlock
> ------------------------
>
> Key: ASTERISK-24540
> URL: https://issues.asterisk.org/jira/browse/ASTERISK-24540
> Project: Asterisk
> Issue Type: Bug
> Security Level: None
> Components: Channels/chan_sip/General
> Affects Versions: 1.8.32.0, 11.14.0
> Environment: CentOS 6.4, CentOS 6.5, CentOS 7
> Reporter: Ross Beer
> Attachments: backtrace-threads-clean.txt, threads.txt
>
>
> We are experiencing an issue where the SIP channel driver pauses and does not allow further registrations or calls to progress.
> Looking at core dumps shows lock waits for app_dial and presence.
> Unfortunately asterisk had not been compiled with the correct settings so I will need to provide further back traces when the issue happens again, however have attached the files I have now.
