Summary:                    Exceptionally long voice queue length queuing to
Local/XXXXXXX
Description: 
Hello

I'm not in the habit to post request but i tried all i can to solve it
without success.

I saw a thread (https://issues.asterisk.org/view.php?id=15609) dealing with a
look alike problem but i'm not sure
it's the same and don't want to disturb it if it is different.


The symptoms are channels cut or communications disturbed - IAX peers
qualification failure, jb sync lost etc.. as showing below:

[Oct 16 17:58:07] NOTICE[2511]: chan_iax2.c:8264 socket_process: Peer
'YYY' is now REACHABLE! Time: 11

the only common point i have are Local channels in race condition.

I have been having such problems for a quite long period and got rid of
them by getting rid of local channels (by moving on others servers not
using them), but for some services i can hardly get rid of local
channels...
The problems disappeared on servers not using local channels but still
goes on with this server.

As https://issues.asterisk.org/view.php?id=15609 i had, some weeks ago, file
write errors, it seems to be related
to hundreds of messages i get while the error occurs, so i applied the "no
duplicate log patch", it seems to have no effect on the number of
"Exceptionally long voice queue length queuing to Local/" messages (i may
have missed something) and worse, the jb resyncing and peers lagged or
unreachable messages still goes on.

I tried the DEBUG_CHANNEL_LOCKS flag but the only lock i got was

=== Thread ID: 1077410128 (do_monitor           started at [16780]
chan_sip.c restart_monitor())
=== ---> Lock https://issues.asterisk.org/view.php?id=0 (chan_sip.c): MUTEX
16726 do_monitor &monlock
0x7f3796d4c620 (1)
=== ---> Lock https://issues.asterisk.org/view.php?id=1 (chan_sip.c): MUTEX
16748 do_monitor &(peer)->_lock
0x7f379c134af0 (1)

I removed DEBUG_CHANNEL_LOCKS flag because of crash that this flag lead
to.

If that problem is considered identical to
https://issues.asterisk.org/view.php?id=15609 don't hesitate to merge
it to this, if different... let me know.

If any information is requested, please let me know...
