The "docId=2147483647" part seems suspicious since that corresponds to Integer.MAX_VALUE and
my index only has 102,013,289 docs in it.  According to the Solr searcher stats page I have:

numDocs: 71,870,998
maxDocs: 102,013,289
deletedDocs: 30,142,291

I took the query that was failing and attempted to intersect my parent query with the child
query to find any problem docs but that came back with 0 results.

After performing an optimize (via the Solr UI) on the index the problem has gone away and
the query that previously triggered this errors works as it should.
