[lug] weird high loads

[Andrew Diederich]

Hmm.  They are running 3-4 odd finds:

nobody   11509  0.0  0.3   832   492  ?  D   May 28   0:00 find / ( -fstype
nfs -o -fstype NFS -o -fstype afs -o -fstype proc -o -fstype smbfs -o
-fstype autofs -o -type d -regex
\(^/S.u.S.E.$\)\|\(^/mnt$\)\|\(^/cdrom$\)\|\(^/tmp$\)\|\(^/us

Nobody's /etc/passwd entry looks sane
(nobody:x:65534:65534:nobody:/tmp:/bin/bash).

I wonder if this is some odd YaST process trying to mount a SuSE cdrom, or
find some rpm's to examine?
