So it just happened again on both machines at the same time and I was<br>
running debug on both servers. I am running OpenSIPS and load balancing<br>
between both servers so I am guessing when the invite was sent to the first<br>
server it was frozen for some reason and then OpenSIPS sent the invite to<br>
the second server and that server was also frozen/deadlocked because of the<br>
SIP message. I noticed on both servers the last log that was posted with<br>
Asterisk deadlocked was the following<br>
<br>
<br>
Asterisk version 11.0.1<br>
[Apr 3 21:39:42] DEBUG[12984] res_timing_timerfd.c: Expected to<br>
acknowledge 1 ticks but got 11805 instead<br>
<br>
Asterisk version 11.2.1<br>
[Apr 3 21:39:50] DEBUG[1854] res_timing_timerfd.c: Expected to acknowledge<br>
1 ticks but got 12423 instead<br>
<br>
<br>
In my last email I posted the debug from the Asterisk server with 11.0.1<br>
version of code. Here is a post of the debug for the Asterisk server with<br>
version 11.2.1<br>

This has to be a bug right? I am thinking of opening an issue on the<br>
Asterisk JIRA system<br>

It just happened again on the 11.0.1 box and I was able to grab a debug.<br>
I am hoping someone can tell me if this is a bug or something wrong with<br>
my config.<br>
<br>
gdb asterisk-bin/sbin/asterisk 29048<br>
<br>
Go here for the debug output<br>

I am currently running two different versions of Asterisk<br>
<br>
11.0.1<br>
11.2.1<br>
<br>
I have noticed the bug occur on both servers.<br>
<br>
The issue is that when I try to dial a phone number sometimes the call<br>
will never go out. I will check the Asterisk server with NGREP and see<br>
that the SIP messages are making it to Asterisk but Asterisk isn't<br>
responding.<br>
<br>
I do the following command "netstat -nap |grep 5060" and see that<br>
Asterisk has a lot under the "Recv-Q" column.<br>
<br>
It usually takes about 10 minutes before Asterisk becomes responsive<br>
again or else before 10 minutes is up I could restart Asterisk and<br>
everything will be back to normal.<br>
<br>
I see in the message logs the following errors<br>
<br>
On the 11.0.1 Asterisk server<br>
WARNING[23723][C-00000010] chan_sip.c: Unable to cancel schedule ID<br>
11473. This is probably a bug (chan_sip.c: update_provisional_keepalive,<br>
line 4406).<br>
<br>
On the 11.2.1 Asterisk server<br>
WARNING[3493][C-0000001f] chan_sip.c: Unable to cancel schedule ID 30810.<br>
This is probably a bug (chan_sip.c: update_provisional_keepalive, line<br>
4683).<br>
<br>
<br>
When I look in chan_sip.c on both servers I see that they are the same<br>
line of code<br>
<br>
AST_SCHED_DEL_UNREF(sched, pvt->provisional_keepalive_<u></u>sched_id,<br>
dialog_unref(pvt, "when you delete the provisional_keepalive_sched_<u></u>id, you<br>
should dec the refcount for the stored dialog ptr"));<br>
<br>
<br>
<br>
What could be causing this because it seems to happen at least once a day.<br>
