High Memory Utilization on Line Card 6748 and 6724

Hello

I am writing to request help with regard to a high memory utilization that we have on a pair of line card WS-X6748-GE-TX and WS-X6724-SFP for a VSS 6500.

I am enclosing a little part of the "show tech"of this VSS 6500 where is possible to see the high memory utilization of the line cards 1/1, 1/2, 2/1, and 2/2, in despite of having some ports in state connected.  In addition of this, the IOS installed on VSS 6500 is s72033-ipservicesk9_wan-vz.122-33.SXI6.bin for checking if there are some bugs affecting the behaviour of the Switch for this case.

High Memory Utilization on Line Card 6748 and 6724

Hi,

Do you have the same problem when there is nothing connected to these modules or only when end devices are connected?

What is the overall CPU utilization?
