Cube Processing Error - Urgent - Thanks

First when I processed cube's (Process Data) using SSIS package I got "Memory error"

"Memory error: Allocation failure : Not enough storage is available to process this command."

I changed "OLAP\ Process \ BufferMemoryLimit" to 30% . I have /3GB setup. and I am using AS 2005 - 32 bit.

When I rerun the package I got olap storage engine error

Errors in the OLAP storage engine: An error occurred while processing the 'Scenario Analysis 2006' partition of the 'Scenario Analysis' measure group for the 'Scenario Analysis' cube from the Risk Reports database.

I don't know what's that, so I run cube process (Full) from Management Studio and got error below while reading data process stoped with following popup message

The trace has been stopped
Unexpected end of the file has occurred. The following elements are not closed: root, return, ExecuteResponse, soap:Body soap: Envelope. Line 13180, position 1. (System.Xml)

Thanks for any help - Ashok
