CRC Error

I noticed the following error message when I logged in to Net Connect today. It is referring to a 3511 unit that I have connected to one of the monitored systems. I've been running a heavy I/O load test on the 3511 over the weekend, but I have not noticed any problems with the unit.

Any ideas on what this might be?
