You mean patching pbs_mom or pbs_server, don't you? I don't see any existing
support for this.

By the way, I don't see why the decision of setting a node down should be
delegated to the server or scheduler. In this case node knows that it is
incapable of executing any jobs. In my view, it would be great if pbs_mom
could report itself as down if node check script returned non-zero exit
code. STDERR output could be used to report a reason. Using STDOUT is less
clean. All that could be configurable (like "down_on_node_check_failure
true" or something).
