    Problem Symptoms:
    The xxx01 run_e_01_word.24779 log shows the following:

    HANDLING DOC NO. - XXX01.007286081 2013-02-06 14:55:11
    Update z98 from z980 : 028000002686
    Update z98 from z980 : 016000011324
    Update z98 from z980 : 026000015273
    Update z98 from z980 : 027000529291
    Update z98 from z980 : 016000636269
    Update z98 from z980 : 037000673531

    Update z98 from z980 : 026000771905
    Update z98 from z980 : 001000803572
    Update z98 from z980 : 001001985422
    Update z98 from z980 : 001011771447


    SQL shows that there are 5,400 z07a records waiting to be processed:

    xxx01@ALEPH20> select count(*) from z07a;
    **** Hit return to continue ****

    COUNT(*)
    ----------
    5436

    At the rate of 3 records/minute it will take 30 hours to process these 5,400 z07a's.

    Cause:
    The slowness has to do with the bib records which ue_01 is processing. Looking at record 7286081, for instance, we see that it is an online resource, with 5xx fields and with an 856 field -- whose subfields u and y are being sent to the WRD and WUR word indexes.

    The most common cause of slowness is large records with large 5xx note fields containing many words.

    Resolution:
    Such loads of online-resource bib records -- or bib records with large 5xx fields -- are probably best done over a weekend.
