    keyword=re: CH scaler getting stuck

    The symptom reported by Rupesh in halog 290035 is the same one we've been having for
    days. He also tells me over the phone that when the CH scaler gets stuck it remains stuck
    for an entire run; whereas when it runs ok it runs for an entire run. Again, the old symptom.

    It's possible the scaler is not cleared / initialized at the start of the run (in "go" routine).
    I've prepared a modified happex3_ts.crl version which checks if the scaler was read at
    least once (data was in FIFO). If not, the scaler is cleared / initialized and a unique errstat
    flag is written into the header so we know this happened. This CRL will be loaded at next
    download. The old one was happex3_ts_ok3.crl and I have backups in ./save_17sep09.

    There are 2 possibilities:

    1. The scaler is bad -- need to replace.

    2. There is something flakey about this crate that it does not clear / initialize the
    scaler at 'go'.

    If my CRL fix does not help we will replace the scaler as the next step.
