             Summary: Call leak in Confbridge
                 Key: ASTERISK-24440
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-24440
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Bridges/bridge_simple
    Affects Versions: 11.13.0
            Reporter: Ben Klang


I've been testing various Asterisk call behaviors with SIPp and with a no-media timeout set to 10 seconds. In every case, if I kill SIPp, Asterisk will eventually terminate the call for lack of media and eventually reach zero calls. However, if I have SIPp call into ConfBridge and then overload Asterisk, those calls are not cleaned up, even 30 minutes after SIPp has been killed.

There is corresponding memory growth which makes me think that the channels aren't getting cleaned up like they should.  In "core show channels" output I see many thousands of calls, even though SIPp is limited to 1,000 concurrent calls.

Some additional notes:

* I do see messages indicating that calls should be getting disconnected, like this: [Oct 19 00:10:09] NOTICE[5874]: chan_sip.c:28942 check_rtp_timeout: Disconnecting call 'SIP/10.3.18.108-00000bda' for lack of RTP activity in 11 seconds
* Many minutes after the test has ended and SIP traffic has stopped, the console is still flooded with messages like this: [Oct 19 00:12:26] WARNING[5874]: chan_sip.c:4258 __sip_autodestruct: Autodestruct on dialog '2472-31726 at 10.3.18.108' with owner SIP/10.3.18.108-000009a7 in place (Method: BYE). Rescheduling destruction for 10000 ms

I've attached the SIPp XML that I'm using for this test.
