asterisk users - Jun 2005 - CPU load about at max when it should be idle.

Hello Everyone,
I am using this box for asterisk, and it seems that as of the last
kernel build I made, when I start asterisk it pins the cpu at 50 percent
and the system at 50 percent.  When I shut down asterisk, it goes 100%
idle.  

Anyone seen this before?

This is a P4-3.0, and I only have 1-2 calls at a time max.

Greg
