------------------------------------------------------------------
The patch is for a function that executes when a call or a channel closes.
My issue is when they are up, I never close any call, just create the channels, and the machine collapses.
Please correct me if I am wrong.
I certainly see the case reported on the other issue.
I start 10 channels, do a netstat -tunap, the RTP ports show. On the other side I do a core restart now, and sure enough, the count "core show channels" goes to zero. But the same ports seem to be allocated, the output for netstat -tunap is identical. They never get freed.
I applied the patch for the issue noted, and it does solve this issue, neither solves that issue.
With or without the patch, the output of netstat -tunap is identical after the channels do close. However, the RTP ports do close after a few seconds, not immediately. I guess that makes the other issue a non-issue.
This issue, instead, is real.

With or without the patch, the output of netstat -tunap is identical after the channels do close. So that issue is also open. We have a FIFO leak and port leak.

> When I originate several hundred calls using a call file, no dialplan, using app Echo() or app MusicOnHold, the calls connect, but when the other side starts to send media, after some 200+ calls I get several errors:
> {noformat}
> "ERROR[2433] res_rtp_asterisk.c: RTCP SR transmission error to 208.78.162.174:34443, rtcp halted Operation not permitted"
> {noformat}
> and the handle count explodes, measured at the end
> {noformat}
> lsof | grep asterisk | grep FIFO | wc -l
> 1025046
> {noformat}
> yes one million and change. The handle count never decreases as long as the channels are open. There are no active calls, only 500 channels.
> The call files are all identical:

> *Note 1:* the caller ID may vary call by call it makes no difference. The issue here is the very high handle count, which slows down and kills the machine, and the errors which show that many calls do not connect.
> *Note 2:* The calls do no across the internet, they go to a local box.
> I need to send as many calls in real life, with media, so this is a killer for my business model.
> If I set up debug=10 and verbose=20, I get thousands of lines identical like this ones
