It would be good to have access to the precise information for "no compatible resources". But, as Stephen says, there are hitches with implementing that. Steve PS: Issue was resolved when I found that CEStatus must be Production. There were other cases - one I can remember concerned sporadic failures of Atlas specific SAMs on another CE, while other SAM tests passed at the same time on the same system. To fix that, we had to reduce the load average of the CE in question by porting it to faster virtual hardware - go figure. -- Steve Jones [log in to unmask] System Administrator office: 220 High Energy Physics Division tel (int): 42334 Oliver Lodge Laboratory tel (ext): +44 (0)151 794 2334 University of Liverpool http://www.liv.ac.uk/physics/hep/
