No job can be submitted and managed at this time. We were informed that software vendor has been contacted, and SLAC Computing Division is working on the issue.
Post-mortem from SLAC comp-out: The problem resulted from a bug in one of the new LSF 9.1.2 daemons. IBM is researching a fix and in the meantime we are still running 9.1.2, but that one daemon has been reverted to 9.1.1. We believe that jobs submitted prior to the problem should have continued to run and should continue to be tracked by LSF.
