PBS is reporting the node as "free", not "busy" and maui is giving you a
warning on this.  It sees "free" with a higher load average as an indication of
something being misconfigured.  If everything is working fine, then just ignore
it.

If you want to fix it, then configure pbs_mom's $max_load and $ideal_load so
that nodes get reported as "busy".
