CAUSE: Nodes in the specified partitions are set to preserve a previous placement, however, nodes from these partitions require the same location resource, but the Fitter cannot place the nodes in that location. Click the + icon to expand this message in the Messages window or in the Messages section of the Report window to display details about the specific nodes that could not be placed by the Fitter.
