a Virtual Machine running Ubuntu 7.10 with just 1GiB of RAM, and after a while, java is using
all the RAM and has entered the swap file. Should I discard the VM and run it all natively
on XP where I have 2GiB of RAM?

Actually, considering 8010 fixtures were run, 9 failing fixtures is
not that bad...
And yes, you'd get a stack for each of the failures/errors; that is to
help analyze the problems - obviously, there is something off still.

I'm not entirely certain what is enough RAM these days, but I can run
on a windows machine with 1.5 Gi RAM, and I used to be able to run on
a box that had 1/4 Gi, although it's been a while I tried it (machine
is slow as well as not much RAM). Ubuntu should be fine too.

What made you think there was still a memory issue, did any of the
error messages on the stacks indicate so?

I'm curious to see an example of the stack traces.
