[SR-Users] PKG memory leak in 4.2.6

[Daniel-Constantin Mierla]

Hello,

it looks like the pkg summary is made by the main kamailio process which
doesn't route sip packets at runtime, therefore it doesn't expose any
potential leak.

Can you add following snipped at beginning of the request_route:

if(is_method("OPTIONS") && src_ip==TRUSTEDIP && $rU=="pkgsummary") {
   pkg_summary();
   sl_send_reply("200", "ok");
   exit;
}

You need to replace TRUSTEDIP with the IP address from where you will
send a SIP OPTIONS later.

After you restart kamailio, let it run for a while until you see the pkg
decreasing enough.

Then send OPTIONS request via sipsak:

sipsak -s sip:pkgsummary at yourserverip

Check the syslog to see if the pkg summary messages are there and if
yes, send them here.

If not, you may need to decrease the value for memlog, do:

kamcmd cfg.set_now_int core memlog 1

and then run again the sipsak command.

Cheers,
Daniel
