This problem may occur when the Maximum Private Bytes attribute is set to a value that is less than 100 MB of physical memory.



RESOLUTION

 * 1) On the Web front-end (WFE) server, click Start, click Programs, click Microsoft Office Server, and then click SharePoint 3.0 Central Administration.

 * 3) In the Excel Services Settings section, click Edit Excel Services settings.
 * 4) Type -1 in the Maximum Private Bytes text box, and then click OK.
