Core issue
The root cause of this error could be a defective module or a mis-seated module. It could also be a chassis problem with this particular slot. This can be a transient issue if it is due to a mis-seated module.
The error message can be one of these two types:
C6KERRDETECT-2-FIFOCRITLEVEL: System detected an unrecoverable resources error on the active supervisor pinnacle
C6KERRDETECT-2-FIFOCRITLEVEL: System detected unrecoverable resources error on active supervisor port-asic
These messages indicate that the system detected unrecoverable resources (due to the First In, First Out [FIFO] problem) on the indicated Pinnacle ASIC or specified port ASIC.
