It's not necessary, but there's not much you can do about it
unfortunately... there are, and always will be lame servers.
Anyway, it shouldn't be a problem performance-vice, or any other way.

Hi group
Thanks for the fast answer.
Yes, I put those lines and stop logging lame-servers.
But I have another question. Is this process decreasing performance on
my server? yes I stopped the logging but is totally necesary the lame
servers?
Thanks in advanced!
