Something of a shot in the dark, but when we had a server with a high 
load average where nothing obvious was causing it, it turned out to be 
multiple df cmds hanging on a stale nfs mount. This command helped us id it:

top -b -n 1 | awk '{if (NR <=7) print; else if ($8 == "D") {print; 
count++} } END {print "Total status D: "count}'

Hope that helps,
Miranda
