I'm very sympathetic, but it will be almost impossible to debug this sort of a problem remotely, without a reproducible example. The only guess that I can make, if you *really* are running *exactly* the same code as you previously ran successfully, is that you might have some very large objects hidden away in a saved workspace in a .RData file that's being loaded automatically ... I would check whether gc(), memory.profile(), etc. give sensible results in a clean R session (R --vanilla).
