SCP-4-DACK_TIMEOUT_MSG --- Error on MSFC

From: Barman, Partha (PBarman@necbns.com)

The 6509 switch crashed, the MSFC was responding, but all line cards were amber, do not know the led status on supervisor. From MSFC cannot see the switch supervisor via "show cdp nei". The error below was showing up on MSFC every 30 secs. A reboot solved the problem.

SCP-4-DACK_TIMEOUT_MSG:SCP delivery ack timeout for opcode=118

Anyone seen this error before, and what could be the problem. I have seen a doc in CCO that says MMLS if disabled on the MSFC could cause this. But we have MMLS running on all vlan interfaces.

One more questions is, even if MMLS is disabled and this error occurs, how could this affect the whole switch and all line cards on the switch turn amber.

Any help is appreciated !!
