Multiple errors while running Region Group

I am getting an error while using Region Group on a large dataset. The errors are specified below:

[INDENT]ERROR 999999: Error executing function.
The table was not found. [VAT_final002]
A column was specified that does not exist.
A column was specified that does not exist.
ERROR 010005: Unable to allocate memory.
ERROR 010067: Error in executing grid expression.
Failed to execute (RegionGroup).

I am currently running ArcGIS 10.1. I have 4 GB of total RAM. The raster I'm processing has 154242 columns and 97288 rows with 30x30 cell size (approximately 500 MB file size). All values = 1 or "nodata". Has anyone found a solution to this than having to process in small sections?
