    Entry number 147106

    keyword=EPICS error messages

    rcServer reports a number of warnings (probably they are not
    errors). These are caused by the EPICS logging scripts.
    It happens in the case below because
    EPICS_CA_ADDR_LIST="129.57.255.4 129.57.238.102"
    when probably only 129.57.255.4 is necessary (main server).
    So, the script finds more than one answer in EPICS land
    and complains (see below).
    However it looks like the data are available from epics and
    are getting into datastream (see below).

    Example message:

    CA.Client.Diagnostic..............................................
    Message: "Ambiguous channel host (multiple IOC's have a channel by that name)"
    Severity: "Warning" Context: "Channel: slia:MV_AO_ESPREADM Accepted: iocvid2.acc.jlab.org:5064 Rejected: 129.57.255.4:5064 "
    Source File: ../service.c Line Number: 910

    Indication data are available (though is zero ok ?)

    [a-onl@adaql2 ~]$ caget slia:MV_AO_ESPREADM
    slia:MV_AO_ESPREADM 0
    but sometimes it is nonzero.

    Indication data are in datastream

    [a-onl@adaql2 data1]$ grep -ai slia:MV_AO_ESPREADM /adaql2/data1/e94107_4870.dat.0
    slia:MV_AO_ESPREADM 3.54466
    slia:MV_AO_ESPREADM 3.82126
    slia:MV_AO_ESPREADM 4.11689

    Note, in parts of the present run, grep shows zeros

    slia:MV_AO_ESPREADM 0
    slia:MV_AO_ESPREADM 0
