Description:Asterisk Doesn't Release RTP ports as it should.
Comments:By: Sarikov Gabriel (gabriel) 2011-10-03 02:19:29.093-0500

only about 22 calls and about 900+ ports open.
By: Sarikov Gabriel (gabriel) 2011-10-03 02:21:57.787-0500

one hour later 18 calls and more the before ports open
By: Sarikov Gabriel (gabriel) 2011-10-03 02:27:55.038-0500

after all ports are used we got this message:
[Oct  2 07:33:58] ERROR[26747] res_rtp_asterisk.c: Oh dear... we couldn't allocate a port for RTP instance '0xb3000bd0'
[Oct  2 07:33:58] ERROR[26747] chan_sip.c: Got SDP but have no RTP session allocated.

By: Sarikov Gabriel (gabriel) 2011-10-03 02:32:17.633-0500

on sip.conf we have :
rtptimeout=60
By: Sarikov Gabriel (gabriel) 2011-10-03 03:20:05.859-0500

added this to sip.conf:

session-timers=originate
session-expires=900
session-minse=90
session-refresher=uas

maybe it will solve this problem.
By: Sarikov Gabriel (gabriel) 2011-10-03 09:30:00.692-0500

didn't solve the problem entirely still stuck sips.

Sounds like you're going to need to provide a backtrace from the running process and 'core show locks' output from the console. I'll post additional messages shortly with information about how to provide that information.
By: Leif Madsen (lmadsen) 2011-10-03 12:51:42.122-0500

Thank you for your bug report. In order to move your issue forward, we require a backtrace[1] from the core file produced after the crash. Also, be sure you have DONT_OPTIMIZE enabled in menuselect within the Compiler Flags section, then:

make install

After enabling, reproduce the crash, and then execute the backtrace[1] instructions. When complete, attach that file to this issue report.

By: Leif Madsen (lmadsen) 2011-10-03 12:52:22.570-0500

Debugging deadlocks: Please select DEBUG_THREADS and DONT_OPTIMIZE in the Compiler Flags section of menuselect. Recompile and install Asterisk (i.e. make install).  This will then give you the console command "core show locks." When the symptoms of the deadlock present themselves again, please provide output of the deadlock via:

# asterisk -rx "core show locks" | tee /tmp/core-show-locks.txt
# gdb -se "asterisk" <pid of asterisk> | tee /tmp/backtrace.txt
gdb> bt
gdb> bt full
gdb> thread apply all bt

Then attach the core-show-locks.txt and backtrace.txt files to this issue. Thanks!

the problem is rtptimeout doesnt work at all
on our previous version 1.6.2(rc2) it always cleared the "zombie channels" after 60 seconds.
i cant do a trace on this machine its production server.

i think its the same issue as :
ASTERISK-18559

restarted asterisk at 5am today(scheduld)
after 5 hours at 10am more then 330 channels aren't released .
even not one rtptimeout message in log.
rtptimeout not working at all.

By: Leif Madsen (lmadsen) 2011-11-01 09:12:39.560-0500

You still haven't provided the backtrace or 'core show locks' output as requested on October 3rd. There will be nothing we can do to move this issue forward without the requested information.
By: Sarikov Gabriel (gabriel) 2011-11-16 07:11:58.218-0600

this issue was resolved on asterisk 1.8.7.1.
no more ports staying open.
By: Richard Mudgett (rmudgett) 2011-11-16 11:23:18.476-0600

Reporter stated that the issue is resolved.
