I think you should run with as many GPs and ziips as your underlying hardware should support. I have been unable to run with 2 GPs and 2 ziips on a machine that is a 2 engine Core i7. Lennie

RMF reports waiting for CPU. Your idea of running with no ZIIPs is a good one, but my license is for 3 CPUs + 2 free ZIIPS, so overall I think it is better to use the free ZIIPs Moving work out of discretionary solved the problem.
