This does not make sense. You cannot allocate 30Gb on a Windows 32 bit 
system, or perhaps you managed to get R compiled with an unknown 
compiler on a 64bit version of Windows?

How much RAM and what size of the pagefile does your system have?
Have you tweaked your system to really use 3Gb per process (if you have

the memory it uses!" how to tweak Windows.
