When you launch your service, do you see a Warning similar to this:
*** WARN: line-number: 30 Top Lovel Async Primitive specifies a scaleout of
numberOfInstances="1", but also specifies a Cas Pool size of
numberOfCASes="6". The Cas Pool size is being forced to be the same as the
scaleout.
If yes,
<analysisEngine async="true">
<scaleout numberOfInstances="1"/> *<<<< REMOVE THIS LINE
FROM Deployment Descriptor*
