If you're using a recent nightly build, you can change the
progress bar into a buffer indicator. The setting is in
the Performance section of the server preferences.

It's worth a try as part of your troubleshooting process.
Some unix systems will automatically lower the priority
of a daemon process to '4.' It is worth checking to see
if that's the case and at least bumping it back up to '0.'

I run 2 slimp3s and a squeezebox from a similar setup
with no problems. 800 MHz, 512 Mb RAM.

Is there a compelling reason why you're using
uncompressed audio? If you compress with FLAC or
some other lossless encoder you'll reduce the amount
of transmitted data and disk space usage by about 50%
with a very modest cost in CPU usage and no
reduction in quality.

... not until the squeeze has native FLAC decoding (which I
believe is on the drawing board).
