UltraGridExcelExporter - OutOfMemoryException

Thank you for the quick response. It appears our implementation is very much the same as yours. The one glaring difference is the application I am trying to export from is very large and takes up quite a bit of memory. I am running memory maps to look at the overall footprint, however, initial research has us well below the 2gig limit.

System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.
