------------------------------------

             Summary: SIP Channel Locks
                 Key: ASTERISK-21386
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-21386
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_sip/General
    Affects Versions: 1.8.22.0, 11.4.0
         Environment: CentOS
            Reporter: Ross Beer
         Attachments: ThreadLock2.rtf

This issue occurs when there are 10 calls per second placed or over. The SIP channel is locking and no longer replying to sip calls.

Originally, this looked like an ODBC realtime issue, however the issue is still present when no realtime peers are in use and realtime has been disabled.

A simple test is setup using SIPP which calls an extension in the dialplan that answers the calls and waits 30 seconds. The calls are then hung up.

This issue sounds like it could be related to ASTERISK-21068, however commands are being run from the CLI.

The CLI shows that there are no replies to critical packets, which suggest that they are not actually being sent.
