I am a linux tech who is helping some librarians debug their dspace.
The complaint is that they are seeing some error pages after clicking on
the "pdf" link after looking at an item.
Whitelabel Error Page
This application has no explicit mapping for /error, so you are
seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).
An internal read or write operation failed
From what I google; there should be an error message in the dspace.log
file, but there are no errors there. (plenty of recent "INFO" and one
or two "WARN" entries, but nothing that looks like it has to do with the
above error.) I verified all the permissions on the assetstore, and
they are the same across the board (all files have the same file
permissions, and all directories have the same dir permissions)
Now, for some history:
This site is relatively new. The school had an older version dspace for
quite some time, but they had a hard-drive go out on them at the same
time that they had some issues with their backup. The short of it is
that, instead of "upgrading" dspace, like we had planned, we ended up
installing a clean dspace 7.6 and re-entering their heaps and piles of
items.
Many of the items which are in their dspace work fine. But a number of
items do not. I am suspicious of the "failing" items, as the dates
(dc.date.accessioned, dc.date.available, which appear to be the dates
that the items were entered) are from years ago. We literally built this
thing less than a month ago and the dates are showing between 3 and 5
years prior. I suspect that someone imported some dumps from the past,
and those dumps did not include the actual items. But that is my suspicion.
Is there a way to verify that the bitstreams (I believe this is the
correct word; I am looking for the files themselves) exist for the items
in the database? Can we dump a list of items without bitstreams? And,
what would be the procedure for entries that no longer have items
associated with them? Delete and re-add, or can they upload a new item
to an existing entry?
Again, I am an IT guy who is mainly helping out, so I apologize for not
being immersed in dspace and knowing everything I should about the tools
available to me.
