Your I/O issue may be due to clients not always closing/releasing connections to the Solr Server, or not having a timeout set on the clients I would suggest that when the incident occurs, you run netstat on the Solr boxes. Chances are, a lot of connections would be in CLOSE_WAIT or TIME_WAIT state. Thanks. Arcadius. -- Arcadius Ahouansou Menelic Ltd | Information is Power M: 07908761999 W: www.menelic.com ---
