            Hi Cliff,
            Thanks. but I can't login the spirit anymore (previously it is okay), I have reopened DCO-5820 to require the access to spirit.

            Hi Cliff

            Is the Core dump at /scratch/dumps at onyx.hpdd.intel.com? I can't find it at that directory.
            Thanks!
