High CPU on 6509 VSS

I have high cpu problem on  6509 VSS(VS-S720-10G).

When VSS was connected to LMS or NMS, the cpu utilization of VSS was very high(MAX 100%).

When they were not connected, the cpu utilization was normal.

I think it is because of SNMP gathering on LMS/NMS.

And I blocked arp table and forwarding table, but there was no change on cpu utilization.

I couldn't find the bug reports and other references.

How can I solve this problem??

Info. IOS version : 12.2(33)SXI1

     device : 6509 VSS(VS-S720-10G)

     cpu utilization : snmp engine (30%~60%) peak, sometimes 100%.
