Since we added seven libraries to our consortium, we have noticed an increase
in ‘strange holds behavior‘ such as one patron receiving two copies of book or
movie, when only one of the two items will actually fulfill the patron’s hold. 
The more we thought about this, the more we realized that it was an issue of
timing: Koha seems to be mishandling simultaneous submissions of data.  For
example two libraries processing their Pick list at the same time or two
libraries checking in items or placing holds at the same time.  

This five-minute video

shows a number of problems that can occur when items are picked, holds are
placed and transfers are initiated at about the same time on different copies
of the same item.

This three-minute video

shows what happens when you receive an item routed to you to fill a ‘phantom’
hold.
