yep strange ... for many sequences it's the same thing. the web server
is under Red Hat 7.2. Could it come from it? This phenomenon with many
network interrupts appeared one day without any important change from
us ...

is it possible to exclude the IP that run this sequence ?

what could I check ? do you think it could be a kind of attack? thanks
because I'm lost ... don't konw what to do with this problem
