Your config was fine as an example for my cluster, thanks, everything works. 
I think it was the missing

QOSWEIGHT             1
CLASSWEIGHT           1

Jobs are running just fine (shouldn't both of them automatically set to 1 ?)

However I experience the very same problem as you do (I need the 
QUEUETIMEWEIGHT set to 1) - the preempted ones stay suspended and instead a 
NEW job from the batch queue is started :-(

I think this is a bug: suspended jobs *should age*, too.
Or automatically get a slightly higher priority than the highest in the same 
class to prevent it from staying suspended and interrupted by jobs from the 
same class.

Could some developer shortly comment on that issue?
