Hi Ronald,<br>
<br>
The crash happens on a reply and not a request - see the frame 14,
where "buf" (the buffer containing the <br>
sip message) shows a reply like text.<br>
<br>
But the is_method() should not crash at all....before diving into
debugging:<br>
1) can you reproduce this crash ?<br>
2) before the crash, do you see any errors in the logs<br>
<br>
Regards,<br>

<div><br>
</div>
<div>I'm using OpenSIPS 1.7.1 and based from the attached back
trace, it crashed when it is trying to parse the method of a
REGISTER message received by the server, triggered by pike
route.</div>
<div>
<br>
</div>
<div>Here is a snippet of my opensips.cfg:</div>
<div>...</div>
<div>
<div>loadmodule "pike.so"</div>
<div>modparam("pike", "sampling_time_unit", 30)</div>
<div>modparam("pike", "reqs_density_per_unit", 75)</div>
<div>modparam("pike", "check_route", "pike")</div>
</div>
<div>...</div>
<div>
<div>route[pike] {</div>
<div> if (($si == $Ri) || ($si == "192.168.1.60") || ($si
== "
192.168.1.61") || ($si == "
192.168.1.65")) {</div>
<div> drop;</div>
<div> }</div>
<div> if (!is_method("REGISTER")) {</div>
<div> drop;</div>
<div> }</div>
<div>}</div>
</div>
<div>
...</div>
<div><br>
</div>
<div>Basically, I just want to check REGISTER messages only on the
pike route. Does anyone have a workaround on this?</div>
<div><br>
</div>
<div>FWIW, should I also post this on the dev list?</div>
<div>
<br>
</div>
<div>Thanks!</div>
<div><br>
