Before doing anything I would upgrade to a gold star release to resolve as many already known about bugs. I would go to 3.6.6E .

The Catalyst 4500 series switches, which includes the Catalyst 4948 switches, has a sophisticated packet-handling methodology for CPU-bound traffic. A commonly perceived problem is high CPU utilization on these switches. This document provides details about the CPU packet-handling architecture and shows you how to identify the causes of high CPU utilization on these switches. The document also lists some common network or configuration scenarios that cause high CPU utilization on the Catalyst 4500 series
