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

             Summary: chan_sip partial unresponsive, one permanent lock
                 Key: ASTERISK-25388
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25388
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_sip/Registration, Resources/res_config_odbc
    Affects Versions: 13.5.0
         Environment: Debian Wheezy amd64;
PostgreSQL 9.1;
ODBC used for database connection;
chan_sip loaded, pjsip not loaded
            Reporter: Stefan Tichy


Nagios/sipsak is sending SIP option requests to UDP 5060;
Another Asterisk Instance (11.18.0) registers using transport tls (realtime config);
Local Asterisk (13.5.0) registers to another Asterisk 13.5.0 using UDP;
no other SIP traffic and no phone calls.

Scenario A: Static configuration for second peer (outgoing registration): works fine

Scenario B: realtime configuration (rtcachefriends=yes) for second peer: after some time asterisk stops responding to the monitoring requests, outgoing registration stops, Recv-Q for UDP 5060 fills up, but incoming registration still works.
"core show locks" constantly shows one lock (see attachement).

Phone calls from the first peer do work. "sip reload" will never finish. "core show locks" output in the second attachement.
