I think it is more likely that you have a bug. Probably you have run out of address space, as that's almost 4Gb if an integer and 8Gb if real.
Can you do options(error=dump.frames) and debugger() after the error message and try to find out what `data' is and what size it is. On Fri, 7 May 2004, David L.
