r.buffer

[Anna Edwards]

I am trying to buffer a very large file at a high 
resolution to ensure accuracy of road definition.

I am using GRASS version 4.1.3 NRCS version operating on
SunOS.    



r.buffer input='proad at PERMANENT' output='proadbuff'
units='meters' distances='3'

ERROR: G_malloc: out of memory


I was thinking that I had buffered a similar coverage very
recently and am not sure why am incurring this error...

Any suggestions??

Many Thanks
