Ok, on my fileserver I'm running Redhat 7.2 with Redhat kernel 2.4.7-10=20
and when I have a large number of people downloading from me at one
time, Samba, ProFTPD, Apache, and SSH all stop responding, and I get the
following in my log, the only thing special I could think about my setup
is I have 3 NIC's bonded together to be load balanced on the same IP,
any ideas?=20
