OK, so there's no available swap anymore (nr_swap_pages=0, Marcelo forgot the
'\n' in the patch). I simply think that with other kernels, you're very short
of memory, but it runs, while with this one, all memory gets consumed, and
since there's no smart oom killer, one process has to get killed.
Cheers,
Willy
