Hi,
The amount of Inactive memory Grows unlimited .... this happens only when
Postgresql (8.1.1) is running... after a few days it "eats" all the RAM
memory ... so I've have to restart the server to free RAM....
This is normal Unix behavior. Leave it running for a few more days and
you'll that nothing wrong happens. Why do you think you need "free"
memory?
Only if the swap memory start getting used a lot you need to worry about
memory consumption.
You should upgrade to 8.1.3 BTW.
Also, shared_buffers seem too low and work_mem too much high for your setup:
shared_buffers = 1000
work_mem = 131076
You should really raise shared_buffers and decrease work_mem: 1000
shared_buffers is probably too conservative. On the other hand 128MB per
sort could be eating your RAM quickly with 18 users connected.
Best regards
