[Mauiusers] insufficient idle procs available ?

We've tried the new configuration (unset resources_default.ncpus and
unset resources_max.ncpus; from from queues and server levels as well) in
the last few days and here are the results:
* For the first time we were able to see that jobs are backfilled! It never
happend before, and this is a major improvment. Though we saw it only in one
of our queues (named 'b_que') it might have happend in other queues as well
(we couln'd verify it yet).
* But - the 'insufficient idle procs available' problem is still there. For
example, at the moment showq shows that there are plenty of non-busy
processors ('65 of 84 Processors Active'), but checkjob says for queued
checking job 228665
