R help - Aug 2012 - random forest using party package

Hi all,
I am trying out with random forest on party package but am getting an error
saying : cannot allocate vector of size 564." What would be the problem?
the
coding as below:
>data.controls <- cforest_unbiased(ntree=1000, mtry=3)
> data.cforest <- cforest(class ~x1+x2+x3, data = Score,
> controls=data.controls)
Error: cannot allocate vector of size 564 Kb
my datasets is of  10 independent variables and 72,000 entries.
what should I proceed?

You appear to have the machine resources to handle the problem, but  
probably have too much other "stuff" (running programs, open windows,
etc)  in your system at this time that is occupying memory, this  
preventing R from having contiguous memory that can hold your data  
object. You should exit R, restart your computer, do not run any other  
applications, ... restart R and redo this analysis.

Have you tried to check memory limit.
You may want to check
Memory.limit()

Although in most of the cases you can extend limit to 4000.

Also as David mentioned try to run only r and force stop others.
