Supervisor restart after flapping interface put in err-disable

[ianmprice]

From what i can tell CR01's active supervisor restarted itself right after CR02's side of the link began flapping and was placed into err-disable to stop the flapping.

What i am trying to figure out is why did the Sup restart itself, and how can this be mitigated in the future?

Attached are the logs from both Devices (6509's) around the time that the issue happened.

Thank you for your help.

Can you provide the crashinfo files for CR01? There should be two files. By default the RP crashinfo will be in slavebootflash: and the SP will be in slavesup-bootflash:

I don't see anything in the logs which would point to the cause.
