RE: duplicate calls to web service

[Mike Krebs <mkrebs@xxxxxxxxxxxxxxxxxx>]

Your NEP (S36 talk!) could work either way (do it in the NEP or submit a discrete job) unless you are worried about a long timeout causing the queue to backup (in which case submitting the job to a separate queue should work well). But, if the requests will all timeout, then it probably doesn't matter as much.

It's been a while since I worked with DDM data queues. The documentation I quick read said that the entries will be removed from the queue when read. Have you verified that is happening? Is it possible you are reading or processing the same entry? Do you have a timeout on receiving the data from the queue? If so, do you check that it timed out and not assume that you need to process an entry? What is the time between your duplicate attempts? If you look in the queue, are you only seeing one request per item?  I don't recall, are you using separate debug logs for each request? Do your duplicate requests occur in the same debug log or in different debug logs?

Lots of questions...hope something triggers a thought.
