Hi Bobby,

Is it a must to use that feature? And sure send me the link off list.

Regards,
Bogdan

Yes, we are using autobridge.  Can I email you/link you the script privately?

Thanks for the help,

Hi Bobby,

I would say the leaking is related to RTPproxy stuff:

  32106 msg_callbacks.c: msg_callback_add(51)
  16053 rtpproxy_callbacks.c: rtpproxy_pre_fwd(51)
  16053 rtpproxy.c: force_rtp_proxy(2848)
  16053 rtpproxy.c: pkg_strdup(2301)

Have you enabled the "rtpproxy_autobridge" option in rtpproxy module ? and what rtpp functions are you using ?

Greetings list,            

We're trying to track down a memory leak with 1.7 R9225+               (It's actually been happening since we've upgraded to 1.7 in general, but we've updated svn a few times and               recompiled to see if the problem goes away).

Here's a diagram of memory usage over a period of time:

http://i45.tinypic.com/ngpqwp.png

Basically we're seeing a package memory leak where package memory is never freed under negligible load.  The               memory used graph looks like a step graph, where flat correlates to a period where we're off peak with traffic.  This will continue for 2-3 days before we see opensips processes start to hang trying to free package memory.  At this point we force an HA restart and the memory dips.
