Feature layer returns error when map panned

In my silverlight app, I have a feature layer created in "OnDemand" mode. The data for this layer is coming from a map service that connects to a SQL Server 2008 table.

I have some filtering controls set up to limit the points returned in the layer. When I have the filter setup so that several hundred points would display, everything seems to work fine (I have clustering set up). The problem is that when I pan the map, I get the following error. Does anyone know what this error means?

This error does not happen when I have the layer in "Snapshot" mode.
