Karl Stoney commented on SOLR-13285:
------------------------------------
A recent development to this is that we did a rolling upgrade from 7.7.1 to
8.1.0, and the issues still presented. I decided to totally reindex the data
on 8.1.0 and we haven't seen the error since, so it's something to do with the
data was being index on 7.x.
I'll continue to run load over the weekend and see what manifests.
