Hi,

One of my servers, that's still running the old Debian Etch,
is been the responsible for de crash of my entire internet
access.

Every time that my internet access gets down, I see an weird
process called 'std' or 'S' always running by www-data user
that consumes all the machine process and network resources.

Is this any know attack? I need to get good arguments to
convince the users of this server to allow me to get it
upgraded.

Thank's
