Passport8600 CPU error

[tijaxu]

On Passport8600 I see the following errors :

CPU5[01/05/07] HW ERROR FAD Mis-Aligned detected, SWIP Reset Status=8. Total=482

CPU5[01/05/07] HW WARNING FAD HwCheck: Fad CRR Failed, Reset swip. Total=44

Number of above errors are shown..

Has been happenning at regular times late in the evening for last few days !! Server backup related buffer issue on the PP8600??

Only way to get the I/O to respond is by resetting the switch. The management of the swithc is not a problem !!

The I/O blades have servers connected.

Any ideas on the cause or how to fix?

Your advise is valued.

Thanks!!

I guess it is the cpu or one of the line modules.
Best is to open a case, trc will ask you do perform some hidden commands to pinpoint to problem

This question has come up before, as Alainv suggests opening a case is probably the best thing to do since the Nortel folks can help you see error counters not normally available.

Here's a previous thread in this group with notes I made when we saw this error:
