Hi Antonis,
While your report could have been a bit more detailed (for instance
describing how did you get into this situation), I'm aware of the
generic problem with failed interrupt delivery that can be triggered
under heavy network load, e.g. packet flood. I'm trying to fix this
right now. I'll be committing some diffs to -current, so I'd highly
recommend updating to the latest snapshot (right now we're in the
end of locking down 6.0) if you would like to test patches.
Regards,
Mike

I've decided to bite the bullet and solved the issue with task
threads and timeouts for now. There's a considerable increase
in performance, but more importantly, I can't DoS the system
anymore. I welcome independent tests, perfomance evaluations
and code review.
Cheers,
Mike
