Symptoms

Missing triples in SPARQL result sets

After using the Joseki Service for a while, it may begin to return wrong query results (i.e. missing triples) for some of the SPARQL queries that are submitted. Running the same queries in the Joseki webapp, they also return results with the same triples missing, but if the query is modified (for instance by rearranging the OPTIONAL blocks) they often return the correct result again. Everything works as normal after a restart of the JBoss server.
