You have to be very careful on what you run on the box, or it may
snap and bite ya. An example from just yesterday:

I use a single computer for both NAT and network scanning, via SANE and
an old HP flatbed. Unbeknownst to me, the swap partition wasn't active.

I set an option in SANE to keep scanned images in memory until they
are fully scanned, thinking it might improve overall performance for
ADF work. Unfortunately the kernel cried wolf before fully shrinking
buffers and cache, and the OOM killer wound up nuking my local DNS server
and gkrellm before fully fitting the image in memory. Hence everybody
started complaining about not being able to access anything. :F
