It proofs code needs to be rewritten. I don't understand why limitation
is on per minute, not per second base. Oh no - I understand. This is
result of the code was written more than 10 years ago. But what I
completely misunderstand is how disabling service for 10 minutes
increases security. It's because I'm green, stupid and brain damaged.
IMHO reasonable behavior is limiting a number of requests accepted per
second without disabling service. But this code became a kind of saint
cow. Only hope is young monsters like xinetd will rid this dinosaur off
as a result of evolution.
