Hello,<br>
<br>
do you get also a log message like:<br>
<br>
CRITICAL: dialog [dlg_hash.c:794]: log_next_state_dlg(): bogus event
4 in state 5 for dlg ... ?<br>
<br>
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.<br>
<br>
Cheers,<br>

sorry it took me more than I expected. Is this

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>

<div>Hi Daniel,<br>

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

WARNING: tm

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>

Any ideas how to continue with
debug?<br>
