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!

1GB shared buffers is far too much. Set it back to like 30000 buffers 
max...
