I have a high system load (> 1.5ish), but a low CPU load (> 80% idle), with the fan running on what sounds like overdrive.
The problem is that I can't figure out what is causing the computer to be dragged down because it is apparently an IO issue, not a CPU issue.
Any ideas? I'm running the latest version of lion. This happens fairly frequently as well.
To clarify, the cpu is mostly idle.
