CPU Hog on C3750G

Hello, 

i have logs on my Layer 3 switch that shows CPU HOGS from SNMP , what's weird is that is causing the OSPF adjacency to come down.

the Switch is a C3750G with IOS 12.2(55)

Is this a cisco bug ?

What can i do to reduce those errors ?

Either try a newer software version if you have a Cisco maintenance contract, or reduce the size/quantity of SNMP queries being made to the device.
