How many rows do you have in the substream that starts with the Generate Rows transform and feeds into the Cartesian join (should only be one row, or your cartesian join will multiple all row numbers from both streams). Also: even though your CSV files aren't huge, the 4 Excel sheets will be zipped XML in the background. That 40MB CSV file might become quite large in memory. File locking the same file 4 times to write to different sheets also won't help on Windows in this case. Metadata injection won't change anything if you try to load these 4 files at once, whether you run that directly or through MDI.
