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