Limits of GRASS

Does anyone know what the limits of GRASS are for raster data ?

I'm trying to import a DEM for our region into GRASS - the data is a 2800
(easting) by 5800 (northing) grid of heights at a 50m grid spacing

GRASS's r.in.ascii reports an error 'Error: Data conversion failed at row
5562, col 253'

Please don't say it size - is it ??

Thanks,

Well I am currently working with a grid of 20800X10800 one minute data
on a global scale and have no problems.

It would seem you problem lies elsewhere, haven't dealt with DEM's in GRASS
though.
