    This entry is a followup to: 164668

    keyword=QRT failure rate this evening

    From scaler analysis in the past 4.8 hours since rebooting ROC23
    (halog 164668) the QRT has failed (apparently) for 3.3 seconds (only !).
    I remind that it failed for 10 minutes straight this afternoon.
    Such a problem is REALLY hard to diagnose !! Nevertheless, if it
    fails more often please page me 24/7.

    Diagnosis:
    1. Suspicous printouts on ROC23 (something about helicity or QRT failing)
    2. Time "sum rule" doesn't add up in scalers (see halog 164654)
    3. GenHelicity printing error messages (experiment needs to be using it).
