[asterisk-users] Troubleshooting load issues

I have an Asterisk box which has an IVR that plays random gsm files. The
box has SSD's and two CPU E5-2695 v2 cpus with 64GB ram. The Asterisk CPU
usage along with the load seems to jump around. With about 500 callers it
hovers between 250-400% CPU (so 2.5 to 4 cores) which seems reasonable.
Every so often the load average spikes. The idle never drops below 85%.
When the load average spikes I see a lot of kworker threads and the CPU
usage tends to (not not always) go up as well. How would I go about seeing
what in Asterisk is causing the spike? The box is locked down and only
takes calls from an OpenSiPS box. There is nothing else running on the box.
