You ask for ten nodes.

But you have five nodes only. So Maui can not find
ten nodes to schedule your job on.

This seems to be the best explanation to your problems.

I have an additional comment. If you want to be able to use
all five nodes in the same job, it might be clever to
add the following line to your Torque (qmgr) configuration

	set queue batch resources_max.nodect = 10

This number should be the maximum number of processors allowed
in your jobs, in your case twice the number of nodes,
because Torque has a strange way of sometimes counting
processors as nodes.
