I have a system whose load is rather high. As you can see from the top output below, CPU usage and I/O is negligible:

I would appreciate any assistance with isolating the cause(s) of high load for when I/O and CPU are not factors.

The high load can also be caused by a few factors:
D
in the process list), that's processes waiting for some I/O.Please check your process list (
ps auxf
), for any processes which may be inD
state, or look weird.
