SptBpduRx constantly shows 60% out of the total 70% CPU utilisation

This happens on two core cat 6500 switches. Customer sees no impact to users. Both switches show this problem and both switches rin CatOS version

8.4(2a)

There is defintely no spanning tree loop in the network.

Will pruning the VLANs help?

Yes, definitely clearing some of the vlans that is not required on a trunk will definitely help that process or lower it. that process means the switch is processing too much incoming BPDU's.
