I've got a couple of these messages in the alert log of my HP ProCurve 4204.

Should I be worried? If yes, how can I correct them?

Thank you.

I would suggest checking your cabling, termination point (rj45 connectors) and make sure your ethernet cables are less than 100 meters

The Ethernet cables are less than 100m but some of them, especially between the workstations and the sockets in the wall might be a bit old ... some might still be Cat5, I'd have to replace them with Cat5e then.

What do you mean with termination points? The sockets in the wall?

Thank you

You could possibly try switching to a different device at the wall jack end to isolate if the issue stays with the original port, indicating a wiring or switch port issue, or moves to the new port with the first device, pointing to the device.

You may also want to have look at the time, when this takes place. If you do not see many I would not be very worried.
If the problem repeated every five min. or so, it could be spanning tree preventing loop between ports.
If correlated with start of a PC, it could be a driver-problem.

At least in one case it actually correlates with the start of a PC ... and in that case I actually get an additional error: Excessive CRC/Alignment Errors ?

Sounds like a good candidate to try on a different jack if possible.

Apparently it was the outlet who created the problems ...
