We have a WS-C4507R+E switch, the runnning software version is 03.08.07.E and the supervisor engine is WS-X45-SUP7L-E.
In the few day ago, the below log is appear:
%C4K_HWFLOWMAN-4-NFEFLINTERRUPT: NFE FL fldMemCorrectedEccErr interrupt. ErrLogEntry: 0, rep[0]: 0x1941888249F2, rep[1]: 0x1941888249F2, rep[2]: 0x965906CF6B8C0234, valid: false, multipleErrorsDetected: true, addr: 0x1283, syndrome: F7, ecc: 0x13A, data: 0x8D13117589C287, 927CA59641B3DA
I didn't find out any bug and cisco document related these log, Does any one could help to explained what this log mean and is there any impact or solution?

- It means a memory error that can be corrected , if the problem persists your options are : 1) power cycle of the switch 2) reseat of the module 3) Have the supervisor replaced (RMA),

If you only see the error once you can ignore it. Occasional memory parity errors are considered normal in all equipment (search for parity errors and cosmic radiation - not a joke). If you have ECC (Error Correcting Code) memory and the OS supports it, then single bit errors can be corrected automatically - which is what is reported here.
If you see the error happening repeatedly then take the measures Marce and Leo have already suggested. It's not clear from the message which module reported the error so you might need to check that with TAC. If you reload the box and re-seat the affected module and still see the errors occurring then that means faulty memory so memory and/or module need to be replaced which you'll also need to talk to TAC about.

I am not sure which line card is generating this error message.
You might want to re-seat the supervisor card. If the message returns, reseat all the rest of the cards.

- fldMemCorrectedEccErr : Looks like memory error(s) on the supervisor , for the moment still recoverable (corrected ECC error)

Hi Marce
Thanks for your reply,
Could you please explain what the "still recoverable" mean and do you have any suggection about next action?

Re-seat line card 4.
