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

             Summary: Memory leak in chan_sip.c with realtime autoclear
                 Key: ASTERISK-22964
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-22964
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_sip/General
    Affects Versions: 11.6.0
            Reporter: ibercom


I have 2 servers with SIP realtime config and asterisk 1.8 and 11 each one.

Server 1.8 have about 2000 register peers without obvious problems.

Server 11 have about 20 register peers and chan_sip.c is constantly leaking memory with each call to the other peers.

The SIP realtime config is the same:

rtcachefriends=yes
rtsavesysname=yes
rtupdate=yes
rtautoclear=yes		<< I think than here is the problem
ignoreregexpire=yes

When Server 11 look for some peer (not register peer) in sippeers table, it works with this info. Another (+1) static (realtime?) object. When the registration expires, memory leak. You can look for the same peer after some time and asterisk allocates memory again and it isn't freed.

I have attached cli-command.txt which shows the asterisk's state with only 112 calls processed.
