I believe most of the time the search capability is disabled when the server load reaches a certain threshold. The last hardware upgrade seemed to have fixed the issue, so perhaps this isn't load-related. Maybe it's the database?
If it is load-related, I fear that the boards might be running up against some pretty steep hardware requirements. They're already running, what, quad Xeons? What's next, 8-way servers? 16-way? Will NASA be the DIS' web hosting service? Or should we just skip ahead and start working on the Beowulf cluster now?
