[OPEN-ILS-GENERAL] ILL templaterecords with Holds not targeting

Hi Mike,
Thanks for the update.  I too suspected indexing/ingest problems awhile back, when talking/emailing with Don re this. Then I believed that that problem had been resolved or a fix had happened.  I thought I would put the issue out to the list to see if others were having the same problem (with v1.4 or whichever).  The most recent example that I sent in to Equinox for investigation, didn't show up on the 'pull holds list' for two days (placed 8/17, appeared 8/19).
Does the "Previous check time" change or is it a good indication of when the item was first found for a hold? Also what is the "targeting  interval expiration"?
Thanks for your response!

The 15 minute time (well, strictly speaking, the configured
re-targeting run time) is just for re-targeting after the targeting
interval has expired.  Initial targeting occurs when the hold is
placed, so something else is going on here.

I suspect that this is another side-effect of the intermittent ingest
issue that has shown up recently.  If the record fails to ingest
properly then some required data (extracted from the fixed fields, and
used to determine the record type) won't be there and can cause the
targeting to exit early.  There is a more aggressive workaround than
the hourly cleanup (Marlene, this has been proposed to your
consortium, in fact) that we believe will address this until we have
completely pinned down the root cause of this intermittent issue.
