Any errors on the interface? I've seen this happen when there are incrementing errors.

I´ve got the same errors on a Cisco 1841. No errors on the interface. Could be this a cable issue?

Can be some cosmetic issue. You can try updating IOS to see if it sill happens.

Is an expert out there who can answer this? I am having this issue as well. Its on the LAN-Interface where the Customer is complaining about broken sessions, basically he's loosing the connection few times a day.

Hello,
Any idea how to troubleshoot/resolve this issue? We have a old 2801 which started displaying the same problem and i see both FE0/0, FE0/1 link messages.
