Hi! What about this?: First use utilization constraints to avoid overloading your nodes (change nodes and each resource). The use priorities for the resources. Now when more resources want to run on a node (C) that the node can deal with, the higher priority resources will succeed. Drawback: Stopping a resource can cause some resource shuffling between nodes. We run a similar configuration with SLES11 for a few years now. If resources are becoming tight, test and development resources have to give way for production resources... Regards, Ulrich > > Thanks in advance!
