(grass-6.4.0svn on Ubuntu JJ 64-bit)
I am trying to "r.proj" the "greek" aster_gdem from the wgs84
(epsg:4326) to hgrs87 (epsg:2100) grass-location. I get the error below.
Anybody else facing problems?

If I raise the resolution of the target location to 90m, then there is
no problem. I assume that this is an error related with disk-space,
memory, etc., right? I have lot of free disk-space and 4GB RAM. Any
other suspect elements here?

Strange (for me): after restarting grass and closing all other apps it
worked like a charm. Does a mail-client, a file browser and some
terminals eat-up that much of memory that cause r.proj to give errors?
