Ultra1 Memory Squeeze

[Nanook <nanook@eskimo.com>]

     I had to reboot ultra1 last night and today; the problems are relating to
a shortage of memory.  Currently the machine has 1GB but it's a busy box and
it's gotten to the point where that isn't enough and Linux's handling of low
memory leaves a lot to be desired.

     We'll be taking the server down later this evening to add memory and bring
it up to 2GB which should resolve this stability problem.
