I forgot to say that it´s a 12GB database...
Ok, I´ll set shared buffers to 30.000 pages but even so "meminfo" and "top" shouldn´t show some shared pages? I heard something about that Redhat 9 can´t handle very well RAM higher than 2GB. Is it right?
Thanks in advance!

RH9, like any 32-bit OS, is limited to 2GB address space w/o special tricks. However, it can access > 2GB for the OS disk cache using PAE if you are running the bigmem kernel.
