Subject: asterisk-classic: Similar issues Followup-For: Bug #386312 Package: asterisk-classic Version: 1:1.2.11.dfsg-1
We've been having similar issues. I don't know if they're related. We are
also running a te110p card from Digium, but the problem seems to be happening
with our SIP phones as well. Once the system starts locking up, any queue you
call gives dead air instead of the music-on-hold--after the initial
announcement (An agent will be with you shortly...), which comes through just
fine. It never connects to anyone either, it just locks up. Also, if anyone
dials in to AgentCallbackLogin(), to log in or out, they also get dead air and
nothing happens.
With a queue call, the console prints this:
-- Goto (queue-overflow,s,1)
-- Executing BackGround("SIP/79-0073b9d0", "menu/tlc-ann-1") in new stack
-- Playing 'menu/tlc-ann-1' (language 'en')
-- Executing Queue("SIP/79-0073b9d0", "overflow") in new stack
It doesn't report starting music-on-hold... but it stays connected until I hang
up.
With AgentCallbackLogin, we see:
-- Executing Wait("SIP/79-00762a70", "1") in new stack
-- Executing AgentCallbackLogin("SIP/79-00762a70", "251||[EMAIL
PROTECTED]") in new stack
and absolutely nothing comes through on the line... but again, it stays
connected until I hang up.
I'm getting the same warning that Andres Junge reported:
Sep 6 16:04:12 WARNING[7256]: chan_zap.c:8505 pri_dchannel: Ring requested on
channel 0/1 already in use on span 1. Hanging up owner.
However, I didn't get any "Avoiding initial deadlock."
The output of show channels illustrates this pretty well:

I'm pretty sure most of those channels have been disconnected. Some I know for
sure:
1. SIP/79 is me; I called into a couple different queues, and then hung up
after a lot of silence. But asterisk still shows my channels open.
2. Zap channels 4, 7 and 9 are from the T1. Those Zap channels are definitely
not still "Up" because the T1 has been physically unplugged now... which we did
*after* we started having problems... in case you were wondering. :-)
Here are the relevant packages:
ii asterisk 1.2.11.dfsg-1 Open Source Private Branch Exchange
(PBX)
ii asterisk-classic 1.2.11.dfsg-1 Open Source Private Branch Exchange
(PBX) - origin
ii asterisk-config 1.2.11.dfsg-1 config files for asterisk
ii asterisk-sounds-m 1.2.11.dfsg-1 sound files for asterisk
ii zaptel 1.2.8.dfsg-1 zapata telephony utilities
ii zaptel-modules-2. 1.2.8.dfsg-1+2.6. zaptel modules for Linux (kernel
2.6.17-2-amd64).
ii zaptel-source 1.2.8.dfsg-1 Zapata telephony interface (source code
for kernel
This also happened previously with Asterisk 1.2.10 and Zaptel 1.2.7 on the same
machine.
So far, it's only been when the T1 is involved that Asterisk goes into this
state. I'll see tomorrow if I can get it to lock up with only SIP calls.
Regular calls SIP to SIP and SIP to Zap, and navigating through the menu, still
work, so Asterisk isn't entirely locked up. It's probably just that a
particular lock that AgentCallbackLogin() and Queue() use is becoming
deadlocked somehow.
Hope this helps to shed some light on things... We will be investigating this
further, but would appreciate any insights anyone may be able to offer.
