ah... i think the bucket size has to be a power of two (and I thought
the kernel would check that the value is correct, but i might have missed
something).

In your reports you said this was a very basic install and did not
mention you changed parameters. Keep in mind for next time, when
you mail a problem report, include all details you can.

BTW you never run out of buckets, you can run out of entries, but
that is a different sysctl variable.
