Try setting transcode_via_sln=no in /etc/asterisk/asterisk.conf and
restart Asterisk. A reload will NOT apply the new value. Setting it to
no seems to smooth out CPU usage on one of my servers.

Hi,
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.
TIA.
Dovid
