Hello,<br>
<br>
I will investigate more -- meanwhile had some traveling. It would
speed up if you can send the backtrace of one process that blocks
when you applied the patch.<br>
<br>
You need to connect with gdb to it:<br>
<br>
gdb /path/to/kamailio _PID_<br>
<br>
replace _PID_ with the pid of blocked kamailio process.<br>
<br>
Cheers,<br>

<div>Hi Daniel,<br>
<br>
</div>
thanks for a reply. I applied the patch and now the
Kamailio just prints <br>
<br>
WARNING: tm [t_lookup.c:1564]: t_unref(): WARNING:
script writer didn't release transaction<br>
<br>
</div>
and than freezes without any log. It does not resend the
incoming "winning" failure reply neither response to any
other messages, not even to a new calls. It just freezes.
All kamailio processes are running and eating the whole
4-core processor.<br>
<br>
</div>
Restart of Kamailio solves this problem.<br>
<br>
</div>
Any ideas how to continue with debug?<br>
<br>
</div>
<div>Thanks <br>

<div>Hi,<br>
<br>
</div>
when I use t_reply("505", "Error"); in my
failure route, the response is not forwarded and
following is written into a log:<br>
<br>
kamailio[26216]: WARNING: tm [t_lookup.c:1559]:
t_unref(): WARNING: script writer didn't release
transaction<br>
<br>
plus next line is written exactly 416000 times
into a log afterwards:<br>
<br>

tags 'd12546d053aadc68o2' ''<br>
<br>
</div>
<div>My point is to change the incoming code from
users and append a Q.850 reason code.<br>
</div>
<div>Is there any other way how to do this or a
way how to fix this?<br>
</div>
<div>I'm using Kamilio 4.0.4 on Debian 7.1<br>

The code is as follows:<br>

exit;<br>

if($T_reply_code == 408 &&
