Provide some snapshots of the top command.
Default settings for PostgreSQL will not use all system memory, they're
actually too memory conservative for most use.
You're missing a TON of details here. I recommend you tell the list
how _much_ memory your system as, in additional to providing your
postgresql.conf file and a top snapshot demonstrating the problem.
My suspicion is one or more of the following:
1) You don't have very much RAM in your system and you're overloading
it with connections or otherwise
2) You're running things other than PG on this system that are eating
RAM.
3) You're being fooled by the fact that Linux will use all the available
RAM all the time (which isn't particularly a bad thing)
