That's exactly what happened actually. I noticed (what I considered) a
suprisingly high "load average" for a server with this specification and
started investigating.
The server is a syslog server that I'm preparing. It's running
syslog-ng and both MySQL and Postgres (neither are used at the moment)
and exporting a filesystem (the logs) via NFS.
There's a perl "logwatch" script that is constantly tailing all the log
files (20,545,009 log lines per day) and if I kill that, the load drops
significantly (down to 0.4 or so). So that's obviously causing the
"high" load average.
The business end of the script forks and runs "gtail -f" on about 5 log
files in the parent and does pattern matching in the child to notify us
of unusual events.

In this case, top shows the system is idling and there's the rub.
I've been conditioned to seeing long term load averages above 1 as a
"bad thing" that needs investigating and dealing with. I'm now
comfortable that (in this case at least), it's caused by a script that
is sleeping or idle most of the time ("top -I" rarely shows this process
or any other for that matter :-).
I guess I just need to adjust my expectations.
Thanks again for the help folks!
