<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">At one point we had a huge spike in inbound traffic towards our freeswitch (valid traffic).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">The traffic is handled by a lua application.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">What we saw was calls hanging in freeswitch while they’ve already been physically disconnected.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">After the huge spike freeswitch behaved normally for a couple of minutes and then suddenly started eating all the available cpu cores at 100%.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">We have some db queries which are fired in the lua application, so these may cause the application to hang, but we haven’t reproduced it yet.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">I’ll setup a test lab with the same configuration and fire sipp at it to see if I can reproduce the issue.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">However, I probably won’t be able to run gcore for debugging. Any other suggestions?<o:p></o:p></span></p>
