Which has nothing to do with BIND.

Or did BIND crash because you ran out of memory?

Install the current version of BIND that isn't susceptible to ZXFR DoS
attacks, that won't fix the above problem, though.

Basically, you're out of memory, or the kernel thinks you are and is
unable to kill processes.  Try the 2.2.18 kernel -- it should fix some
of the VM oddities.
