<tt>Hi Ben,<br>
<br>
<tt><tt>The BT indicates a double free for the accounting context
- and I notice<tt>d you use 2.4<tt>.1 version. <tt>And yes, <tt>t</tt>here
was an issue related to acc context, issue that was
fixed starting 2.4.2<tt>. So, could you up<tt>grade to
the latest 2.4 and see if the crash still <tt><tt><tt>happens</tt>
? As I think the fix is already there.<br>
<br>
<tt>Regards,</tt><br>

picked out a Call-ID from the crash data and took a
look in our tracing. I have uploaded it here: <a

<p class="MsoNormal"><span style="font-size:11.0pt">It
appears that a downstream server was extremely
lagged and failed to respond to an INVITE. We sent
the INVITE to another server and the call was
connected, but then eventually the original server
“caught up” and sent a burst of 200 OK responses.
The crash seems to have occurred processing the ACK
to one of these responses.</span><o:p></o:p></p>
