Since I could not diagnose the DAQ problems from home I came in.
On the R-arm I rebooted everything from scratch and it works fine again.
The only thing I did differently is that I made sure the ET system was killed off.
Oddly I could not kill it from the a-onl account so I used "root" to "kill -9".
On the L-arm the problem is two-fold: 1) The normalization scalers (both ungated
by helicity and gated by helicity) read back zero. 2) Deadtime is very high, e.g.
~250 Hz observed rate for ~500 Hz pulser (--> 50% DT). This is probably related
to the scaler problem (problem #1) if there is a timeout for readout. I tried
rebooting the trigger supervisor crate (TS1) several times. The solution should
be to power cycle the TS1 crate. The experiment doesn't want to take access on L-arm
now, so L-arm DAQ is presently running with no scalers and high DT.
