Running 'top' shows me that my memory gets used up (as I would kind of
expect), but 'used swap' never leaves 0k. The swap is simply not being
used.
I tried 'swapon /dev/hda3', but got 'device or resource busy'
Can anyone think of what I might be doing wrong?
Well, one thing to keep in mind is that ant is a java process, and
java processes have a maximum heap size that is set at the time the
process is launched that is independent of the available memory in the
machine. By default, this is often set to 256meg. So you may well be
running out of java heap before actual physical memory is exhausted.
