Sorry about that - brown paper bag time...
swappiness was (coming from 2.6.8) still set to 0. As usual setting it back to
its default of 60
fixes the problem...
Would it be worthwhile to include the swappiness value in the OOM-killer's
report?

Hi,
we are running some pretty large applications in 32bit mode on 64bit
AMD kernels (8GB Ram, Dual AMD64 CPUs, SMP). Kernel is 2.6.11.4 or
2.4.21.
Some of these applications run consistently out of memory but only
on 2.6 machines. In fact large memory allocations that libc answers
