Run top, hit 'F' to select a field to sort on, then n for %MEM. This
will show you what processes are sucking up your RAM.
Also run free -m to see how much memory you have, how much virtual
memory you have, and how much of it is in use. Make sure you have as
much as you think you have.
OK, i had to restart the server as there was critical services running
on it... After rebooting and running the commands above:
