[Archivesspace_Users_Group] Index errors

[Tom Hanstra]

During some work done over the weekend as we were upgrading from 2.8.1 to
3.4, I ran into some indexing errors. I was getting a repeated set of
errors like this:

I first attempted to clean up and recreate the directory it mentions:

/home/app/archivesspace/data/tmp

and that built different directories. But the errors continued to repeat. I
finally had to go to a full backup I had made and restore the entire data
directory. That allowed indexing to get back to working properly.

My questions:
- What was the actual problem here?  What file was hitting an EOFError if
these are files that are in the tmp subdirectory
- Are there any ways to address this other than to re-index (or use a
backup as I did)?

Thanks for any ideas,
Tom
