The physical memory is 2GB and the .RData (renamed .old.RData) size

% ls -lh .old.RData
-rw-r--r--   1  531          316M May 14 18:58 .old.RData

Also, it fails in both Linux and Solaris (the message above is
from Solaris. If memory doesn't fail me, the message in the
Linux box was slightly different, in particular, the first line).

Suggestions? Thank you very much,

Alvaro Novo
