RHIC Running:  Many difficulties made for inconsistent running   This included a PLC failure for the 10 o'clock cryo.  A Yellow loss monitor that was probably real, and a Blue loss monitor that dropped 4 stores before the troublesome loss monitor was masked out of the interlock.  At the same time, the Blue intensity was reduced to allow for a store to be completed.  This finally got the beam back, without a fundamental understanding of the source of the problem.  Blue intensity was brought back up in the next stores, so it was most likely a loss monitor problem that caused the dumps.
