We've had an issue recently with holds disappearing. It's been difficult to pinpoint or replicate, but so far the common factors are holds for items when there is only 1 item record attached to the bib record. Some tests we've done show that if a hold for one of these items isn't triggered withing a day or two, the hold is removed.
Is this related to a setting that we can change, or is it a Sierra malfunction. I didn't see anything about it in the known issues documentation.
We are currently on Sierra 4.3.0_11
