Preparing for reinjection of beam. 7:40 => new fire alarm 2. Run 2145 (started in previous shift) and a few test runs 3. Around 1:50, noticed event rate = 0 in DAQ. Stopped the run. Got a lot of EventBuilder error. MC called to ask why scalers were stuck. Reset the scalers in LumiScaler. Individual ZDC and BB were counting, the others remained at 0. Visual scalers in FEH were stuck too. Reset them but remained at 0. Called Konstantin and Dana. Dana came around 3:00. Cycled power of some crates NIM bins and got scalers back. See logbook for details. Got the DAQ work when only camac and fb4 partitions were selected => TPC and DC partitions screw the DAQ. Sent an email to Bob Scheetz to check TPC readout. ------------------------------------------------------------
