[GRASSLIST:6771] Promble with displaying data

[nilarcs]

Hi everybody

I met one promble with displaying data. I have one data import from
shapefile which total size is about 77Mb. I added this data to GRASS's
GIS Manager , then displayed it.  But in the monitor they are not 
displayed all , only a part. Now I found some message in terminal ,
it's said that

WARNING: coor files of vector 'test6 at PERMANENT' is larger than it should
         (14828770 bytes excess).

It seemed that the data is too big to display. Is it right? But I
think 77Mb data is not too large in GIS data.Maybe I should setting
something , but I don't know.

How can I display the whole data ? 

Thanks in advance!
