do you have heavy traffic on that instance? How many children have you 
configured?

What you can do is to attach with gdb to a process using lot of CPU and 
do the backtrace:

gdb /path/to/kamailio __pid__

Replace __pid__ with the PID of process eating the CPU. Then run bt

It may be a deadlock/infinite loop somewhere. I saw three processes in 
top, others were down with no much cpu usage. Is the SIP routing going 
fine anyhow when CPU usage is high? How do you solve it, by restart or 
it just appears from time to time and solves itself periodically?

Cheers,
Daniel
