Without knowing your OS, no. If I make the assumption that you are on 
Windows and a further assumption that you have not set the targets field 
in your R shortcut to include --max-mem-size=2000M, then this may be a 
configuration problem (you still may not have enough RAM to run expresso 
on say 50 hgu133plus2 chips). If you are on an OS that is more capable 
vis a vis memory allocation, then you are simply running out of memory, 
and need to get more RAM.

Best,

Jim
