--- Comment #20 from Michael Tuexen <tuexen at freebsd.org> ---
One could add some additional logic to only accept syn-cookies if either
syn-caches are not used or if they are used, there has been recently some
entries dropped due to memory shortage.

That would fix this issue when the syncache did not overflow recently.
