Paging slips with in transit status

["McClellan Jr., Michael C." <MMcClellan@xxxxxxxxxx>]

Does anyone have a simple explanation for why a branch would be getting
paging slips for items with an in transit status?  I'm working from the
initial assumption that the status line on the paging slip is showing
the item's status at the moment the paging slips are being printed and
not the item's status when the hold was originally placed. 

I can not figure out why the agency is getting slips for items in
transit as the actions that put it in transit, i.e. checking the item in
at another location, running the clear the hold shelf program, or
manually changing the status which I have ruled out in these cases, all
imply the item was not at the branch to begin with and should not have
been paged.  

So then I wondered if their copy was checked out and another library can
not find their copy, then there might be a window in which the transfer
the page program sees the now returned copy (which is in transit back to
it's home) and transfers the page to that particular copy.  However when
I try testing this it does not show a in transit copy as being eligible
for paging and the documentation says that only items with "-"
(available) can be transferred.

The other possibility would be running the clear the hold shelf program
which puts the item in transit back to the owning agency.  So if there
were no outstanding holds when that program is run, there again would be
a window in which the item is in transit back home and a new patron
places a hold.  But again the in transit status should block that copy
from being paged.
  
So you would be doing me a great favor and reducing the sizable headache
this is causing by coming up with some explanation that I have missed.
