ASA 5520 CPU untilization is 100 %

We have configured 20 route in ASA 5520.

The CPU usage goes to 100 % at the moment when we add a specific route.

route inside 10.254.101.0 255.255.255.0 10.254.102.254 1

This is the same case when we add this route at the first cli or as the 10th cli or the 21 cli (errespective of the position of cli)

There is an another route out of which 20 routes we have configured is

route inside 10.254.103.0 255.255.255.0 10.254.102.254 1

this is just for your information

We are using the image file : asa821-k8.bin

device manager version is 6.2(1)

RAM : 2048 MB

flash: 256 MB

The normal case if we dont add the problamatic route , then the CPU utilization is only 2 %.

Kindly help us to figure out the route cause of this issue..

Dear

  when you are using maximum routes in a single device, the CPU utilization should be increasing to higher...

thanks ..
