Hello,<br>
<br>
the backtrace is from the MI process, not a SIP worker. That process
does not handle sip traffic.<br>
<br>
Before you start testing you can do 'kamctl ps' and see which are
the sip workers and get the backtrace from those pids.<br>
<br>
Cheers,<br>
Daniel<br>

<div> Hello,<br>
<br>
does it block for few seconds and then goes on, or it
locks after few seconds and stays locked?<br>
<br>
If the second, attach with gdb to the pid of the
locked process and get the backtrace.<br>

<div>Hi everyone,</div>
<div><br>
</div>
<div>I believe I've run into a problem when
using dlg_end_dlg (with mi_datagram ) called
from an external perl script with perl_exec()
.<br>
</div>
<div>Kamailio just locks after a while (few
seconds) after disconnecting a call.</div>
<div>Some parts of my debug log can be found
here:</div>

<div><br>
</div>
<div>The problem was observed while performing a
stress test.</div>
<div>Is it a good idea to call dlg_end_dlg()
like that or I can kill an established dialog
from the routing script in some other way ? </div>
