Solr reindex stops prematurely when starting Collective Solr for Plone

My team is working on a search application for our websites. We use Collective Solr in Plone to index our intranet sites and documentation. We recently created a shared blob store on our test intranet site instance because Solr did not index our PDFs. This seems to work, every time I run the reindexing script (@@ solr-maintenance / reindex) it stops after about an hour and a half. I know this is not indexing our entire site as numerous pages, files, etc. are missing from the Solr dashboard when running a query.

The warning below is the last thing I see in the Solr log before the script stops. I'm very new to Solr, so I'm not sure what he is pointing to. When I run the same script on our documentation site, it exits without error.

I hope someone out there can have more experience with Collective Solr for Plone and can recommend some good resources for debugging this issue. I've searched a lot lately but didn't find much useful information.
