I was intending to try and fix this either today or tomorrow. There is also a problem with diskless swapping where the machine will spontaneously reboot as soon as it starts paging. A workaround for this is to pre-allocate the swapfile using dd rather than just creating an empty file (as the FAQ suggests). -- Doug Rabson, Microsoft RenderMorphics Ltd.
