Ok, I did get a little more information about it from here:
http://yonik.com/solr/optimistic-concurrency/ but I really don't know why
the version number is conflicting. I'm running the only process that is
changing documents, and my process is to read the document, add a field,
and write the document. The records were all created at the same time with
similar data, and are all being updated for the first time, again with
similar data.
I did happen to stumble on the atomic updates feature, which is new to me,
and is probably a better way to do what I need.
