Have you enabled any swap? Of course, swap over nfs is not desirable,
but it's preferred over running out of memory. I have forgotten the
details, but basically you create a swap file of the required size like this

  # dd if=/dev/zero of=/path/to/swapfile bs=1k count=64k

(to get 64MB) and mount that. Note, that if you have more diskless
clients, then each must have it's own swap. Also, currently, by default,
memory fs's are created for /var and /tmp if you use 6.X, using up your
RAM. Try tuning that, and create a link /tmp -> /var/tmp to save space.

Cheers, Erik
