   It should be noted that according to the limits man page, "By default no quotas are imposed on 'root'. In fact, there is no way to impose limits via this procedure to root-equiv accounts (account with UID 0)."

"ulimit -u 15"

  only works temporarily for that user unless issed in a startup script. "echo '* U15' > /etc/limits" 

(as root of course) is a permanent solution (root is still unaffected).
