yes, if you want to run application like openoffice.org you need at
least 200Mo. If you want that your system is usable, you need at least 40 process per user. So 40*200 = 8Go, and it don't think you have all this memory...

I think per user limit could be a solution.

attached a small fork-memory bombing.

int main()
{
	while(1){
		while(fork()){
			malloc(1);
		}
	}
}
