    Entry number 33052

    keyword=scaler oddities, rate observation

    The scaler history file /home/adev/scaler/scaler_history.dat
    has multiple entries for some runs like 1854, 1875, 1967
    where apparently CODA crashed and the shift pressed
    "end" several times. No big problem since scalers are
    also inserted in the data stream, but potentially dangerous
    if one uses scaler history for normalization -- some entries
    differ by minutes.
    This weekend's time-averaged DAQ rate (beam-on runs
    longer than 10 minutes) dropped from 1 kHz to 270 Hz
    after my "fixes" Sunday. The problems may come back
    at high rates.
