Re: [SR-Users] t_reply in failure route with dialog module

Hello,

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.

You need to connect with gdb to it:

gdb /path/to/kamailio _PID_

replace _PID_ with the pid of blocked kamailio process.

Cheers, Daniel

Hi Daniel,

thanks for a reply. I applied the patch and now the Kamailio just prints

WARNING: tm [t_lookup.c:1564]: t_unref(): WARNING: script writer didn't release transaction

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.

Restart of Kamailio solves this problem.

Any ideas how to continue with debug?

Thanks

Hi,

when I use t_reply("505", "Error"); in my failure route, the
response is not forwarded and following is written into a log:

kamailio[26216]: WARNING: tm [t_lookup.c:1559]: t_unref():
WARNING: script writer didn't release transaction

plus next line is written exactly 416000 times into a log afterwards:

kamailio[32685]: CRITICAL: dialog [dlg_hash.c:794]:
log_next_state_dlg(): bogus event 4 in state 5 for dlg 0xb4af6588
[2575:7017] with clid '121d44f0-6555f4c8' and tags
'd12546d053aadc68o2' ''

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


The code is as follows:
failure_route[MANAGE_FAILURE]
{
        if (t_is_canceled()) {
                exit;
        }
        if($T_reply_code == 408 && isflagset(10))
        {
                xlog("Ringing timeout");
                append_to_reply("Reason: Q.850;cause=28\r\n");
                t_reply("505", "Error");
        }
}
