[Mauiusers] QOSFEATURES not working?

I have a problem with forcing QOS'es to honour features requested. My
config file looks this way:
CLASSCFG[cluster_1n_24h] QLIST=light QDEF=light
CLASSCFG[cluster_8n_24h] QLIST=bulk QDEF=bulk
CLASSCFG[test] QLIST=test QDEF=test
Trying to say - for given class (which is transferred to maui as queue
name from torque) use given QOS (light, bulk or test). It is done this
way to restrict maximum number of processors available for given classes
and thus to protect cluster from being flooded by small, long jobs
blocking large ones for weeks - what is taking place right now. This
part works. But one class - test - which consists of several nodes for
job testing purposes, i.e.for very short jobs. They should be not used
by light and bulk QOSI have to restrict QOS'es for light and bulk to not
run on that test nodes and test to not work on productive nodes.
QOSFEATURES looks ideal for that. The manual is completely
straightforward here - "specifies which node features must be present on
resources allocated to jobs of the associated QOS", for example
"QOSFEATURES wide interactive - (jobs with a QOS value of 2 may only
run on nodes with the feature 'wide' AND the feature 'interactive'
set)". But it doesn't work for me. Jobs from any QOS can run on any node
no matter what features is placed on the node.
diagnose -n reports proper features by the node. diagnose -Q shows
MAXPROC, but there is no sign of any restriction by feature in its
output. Everything is on maui 3.2.6p11.
Anyone being successful on turning QOSFEATURES restriction on?
