I didn't change the postgresql.conf settings:
#sort_mem = 1024                # min 64, size in KB

Well as I said before the box is almost out of control: disk is caching 
intensively; I run X Windows and the mouse can not point a shell... very 
bad. The only thing I see is that cache is filling quickly with 
xosview... and then X become frozen (or better said extremely slow).

Abou the logs:
I sent the PHP error messages to a file, and yes there are errors:
pg_connect(): Unable to connect to PostgreSQL server: FATAL:  
Non-superuser connection limit exceeded
or
pg_connect(): Unable to connect to PostgreSQL server: FATAL:  Sorry, too 
many clients already


Thanks
