AIX system with high CPU used after reboot(SCSP)

Dear All:

I have  an AIX7 server with SCSP Agent 5.2.9MP6 installed for few month.

The only policy is File Watch for 6 document, report frequency is less then 30 /per hour.

Didn't do any change before and after reboot.

It's good work in past days,but after it reboot in two days ago,the CPU use by Kernel always go to 90％UP.

When I stop sisidsagent service it return to normal.

There are 20 servers,only one server have this situation.

Does anyone have experience like this or know how to fix it, please tell me.

Thank You!

（red is the CPU that Kernel used）
