Hello,

do you get also a log message like:

CRITICAL: dialog [dlg_hash.c:794]: log_next_state_dlg(): bogus event 4 in state 5 for dlg ... ?

The warning itself should be harmless. Maybe you can grab all the log messages with debug=3, that will help to get more hits about what happens.

Cheers,
Daniel

Hi guys,

was this issue resolved?
I encountered this issue also (4.0.5), in failure_route, i used t_reply("404","not found")
never sent out, instead i get this in logs,
WARNING: tm [t_lookup.c:1564]: t_unref(): WARNING: script writer didn't release transaction

    Hello,

    the backtrace is ok for the moment. I will look over it and come
    back with results.

    Hi Daniel,

    sorry it took me more than I expected. Is this sufficient?
    Meanwhile I found out that this happens when fr_inv_timer
    triggers and dialog module is turned on.

        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

            Hello,

            can you try attached patch?

            Let me know if all goes fine and I will commit it to the
            repository.

            Hi,

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

            t_unref(): WARNING: script writer didn't release

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

            kamailio[32685]: CRITICAL: dialog [dlg_hash.c:794]:

            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");
                    }
            }
