Every hour we are seeing 100% utilization of 1Gbps links on about 15 ports. It seems to be nearly impossible to trace because the ports that are at 100% utilization differ each time this occurs.
There are about 4 or 5 sepearte vlans involved, and they are all in different areas of the facility, the problem is isolated to a single card, none of the other cards are experiencing issues, there is nothing specifically different as well.
Is it possible for a malfunction of the card to cause this issue?
