Ethereal is pretty cheap . . . free (www.ethereal.com). For unix, try www.insecure.org.

By the way, (NT) have you looked at Task Manager / Processes to see if there's a process consuming CPU? Unix also has some ways of checking process CPU consumption, although Im a little less familiar with them. But I think Linux has TOP, vmstat, and iostat.

Good luck.

Have you done a protocol trace to see the content? Or the source and destination addresses / ports?
