Bug Details

Views: 3

Description

Symptom

A Cisco Catalyst 4500 Switch may see logs: %C4K_SUPERVISOR-2-SOFTERROR: memory inconsistency detected: 0xXXXX every hour

Conditions

The error is triggered by a bit error in the FPGA memory. The error will occur every hour until a reload is performed. Note that the persistence of the error does not indicate new occurrences of the bit error, it is just repeating the same error until a reload is done to clear it.

Workaround

Reload the router

Further Problem Description

The fix for this bug CSCuc23037 adds additional testing so that, if the bit error would be impacting, a syslog error is generated, and if it is non-impacting, it is only logged to the obfl. This fix is only applicable to the K5 based Catalyst 4500 supervisors which are the WS-X45-SUP6-E, WS-C4900M, WS-X45-SUP6L-E, WS-C4948E, WS-C4948E-F. For K10 platforms (Supervisor 7 and 8), see CSCuq09636.
