Exception after partial load

I had a load csv command running that failed with out of memory, and now when I try to query I get this:

Neo.DatabaseError.General.UnknownError: org.neo4j.io.pagecache.impl.FileIsNotMappedException: File has been unmapped: /var/lib/neo4j/data/databases/graph.db/neostore.counts.db.a

Is this a known exception? How can I fix this?

I got an answer on slack, that worked.

Delete neostore.counts.db.a and neostore.counts.db.b files and restart.
