------------------------------------------------------------------

The problem is back. I am using SIP, not PJSIP. With 220 open calls, playing tons of voice prompts, it is a free roulette over the phone, you may test it 1 573 764 2870 (free free free)
 lsof | grep asterisk | grep FIFO | wc -l
646110
after like 1/2 hour.

Note: SVN-branch-11-r432098M has the same issue, so this is a regression issue.
I think this may be a new leak, unknown so far. I went back to rev SVN-branch-13-r431807M and with 120 calls it shows
lsof | grep asterisk| grep FIFO | wc -l
190950
The only thing I do is playing prompts and constantly reading variables
Note:
This is turning simpler. In a completely empty, not even a single line, dialplan, with 

SIP/demo-0000037d    (None)               Up      Echo()
SIP/demo-0000037e    (None)               Up      Echo()
SIP/demo-0000037f    (None)               Up      Echo()
501 active channels
0 active calls
0 calls processed
lsof | grep asterisk| grep FIFO | wc -l
1028105

This is SVN-branch-13-r432154M
Is this normal?
By the way, there are no codecs loaded that do not come with Asterisk.
All the channels are originated using a call file and the app Echo.
I did some experimentation, and it shows that if If I open 500 calls, and in the receiving end use the app Echo(), same in the sending box, the count is 44 on both ends. Two boxes, one originates 500 calls and drops them into Echo(), the other one receives them and also Echo(). No FIFO problem.  

Can somebody give instructions as to how to debug this inside gdb?

>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Resources/res_timing_pthread
>    Affects Versions: 13.2.0
>         Environment: Current Debian (jessie/testing), i386, up-to-date
>            Reporter: Matthias Urlichs
>            Assignee: Joshua Colp
>         Attachments: timer.patch
>
>
> Pthread timers are never deallocated because their link into the pthread_timers chain is never undone.
> This causes a file descriptor leak (at least two per incoming call).
> The locking in this patch probably needs review; the ao2_unlink() call does not. :-P
> \[Edit:\] *Inline patch removed*
