It used (at least) to be possible to save a workspace that needed more
memory to load than it occupies and so you could hit the maximum memory
allocation when trying to load it.  If the .Rdata file looks comparable in
size with the RAM (and remember .Rdata is compressed) it might be worth
increasing --max-mem-size on the command line and trying again.
