[SR-Users] set_body_multipart and memory leak

[Sergey Basov]

Hi, All.

I have some problems with pkg_memory leak.

After each call used private memory of the "udp receiver" process
increases at 2500 bytes.
On test environment I hav set it to 2Mbyte, but it is full after 700 calls.

I need to modify SDP in invite and other packets.
When I do

====================================================

if(has_body("application/sdp"))
   set_body_multipart();
   if (msg_apply_changes())
    {
       xlog("L_INFO", "ISUP 1 Changes Applied Succesfully");
    }
}

record_route();
dlg_manage
route(RELAY);

====================================================
