How can the loadavg shoot up (from ~1 to ~20) without a corresponding

loadavg is based on number of processes vying for cpu time on the runq; the
number of over-all processes on the system is not really

Each time I access USB disks, load goes through the roof.
Nope, it's a rack server in a secure remote location, with no
peripherals at all attached. Only attached cables are power and
network.

I did a little research on the loadavg number, and my understanding is that
it's simply a function of the number of tasks on the system. (There's
some fancy stuff thrown in for exponential decay and curve smoothing and
all that, but it's still

Start digging into your array. Perhaps you're starting to lose a drive and it's
running daily integrity checks or
something. ie, dropping in and out of the array or the like..
I have a dual Xeon 5130 (four total CPUs) server running CentOS 5.7.
Approximately every 17 hours, the load on this server slowly creeps up
until it hits 20, then slowly goes back down.
The most recent example started around 2:00am this morning. Outside of
