The addition of 16GB of memory to the database server caused an unexpected problem

The addition of 16GB of memory to the database server caused an unexpected problem. It exposed a bug in the 3ware Linux disk controller driver which took many hours to identify and understand. The project was back up and running soon after 13:00 UTC today. We do not anticipate any further issues, and apologize to project participants for the unanticipated downtime. On the positive side, the memory upgrade will make the Einstein@Home web pages and project forums snappier and more responsive.
