Hello Paolo,<br>
<br>
just commenting on the first issue:<br>
<br>
So I understood you correctly, after the stress-test you observe a not ending <br>
CPU load on the Kamailio server, even without load?<br>
<br>
Maybe you can have a look on the CPU consuming processes by attaching e.g. <br>
"strace" to them at the next occasion, to see what they are doing.<br>
<br>
Best regards,<br>
<br>
