My set-up is not identical, but similar (G5 2x2 gHz, RME Digiface,
Nuendo), but it remained somewhat capricious untill I added RAM to a
total of 3.5 Gig. After that it became very reliable.

The Console (system.log) showed that the actual available RAM was not
necessarily consistent with what you really load into it (samples,
files, etc.). So you really need much more RAM that you would think in
order to always have some available.

Hope it helps...
