Tim Underwood commented on LUCENE-7674:
---------------------------------------

Thanks [~jpountz]!  I'm trying to figure out if this an issue on my side (very possible) or
if it's a Solr or Lucene issue.

All my indexing goes through Solr (via SolrJ) and as far as I can tell I'm not attempting
to index any child documents without a corresponding parent document.  I'm not even sure if
Solr or SolrJ would allow me to do that.

Does it make sense that optimizing the index would cause the problem to go away?

I think I was able to snag a copy of the index that was causing problems before the optimized
version was able to replicate.  Any suggestions/pointers for trying to track down whatever
docs are problematic?  Will running CheckIndex on it tell me anything useful?

> 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 error works as it should.
