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

             Summary: chan_sip deadlocks with TCP connections
                 Key: ASTERISK-23623
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-23623
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_sip/TCP-TLS
    Affects Versions: 11.8.1
         Environment: Gentoo, Asterisk 11.8.1
            Reporter: Artem Makhutov


My asterisk box has 3 x Cisco 9971 and 1 x Grandstream GXV 3000 Phone all connected via TCP.

The deadlock happands almost once a day and requires a restart of asterisk.

There is always a lock in do_monitor and usually several locks on handle_tcptls_connection.
