    keyword=EPICS Information in Data

    Since Friday evening, there has been a problem with EPICS information
    being recorded in the datastream. The first sympton occured for the
    R-HRS run number 20693. In the start-of-run file, the EPICS variables
    appear to be fine at 17:32. By the end of run, all the variables report
    back that the channel is invalid at 21:24.

    I noticed this yesterday and saw that the EPICS_CA_ADDR_LIST variable
    only contained one of the valid IP addresses. I choose not to reproduce
    the addresses here. I added the second yesterday at 13:40, which fixed
    the R-HRS problem. I should have checked the L-HRS epics loggers, but
    didnt' since the variables were appearing correctly in the start and
    end-of-run files.

    This morning at 8:40, I looked at the epics loggers for the L-HRS and
    found they also contained only one of the valid IP addresses. I updated
    the IP list and have verified that the variables are now being recorded
    correctly starting with run 3503.

    This problem affects L-HRS runs: 3345-3502 and R-HRS runs: 20693-20697.
