Well, I read your mail after sending this out and I also agree with you. In my exp when a UDP flood comes in, the kernel will also pump out the message, usually at a smaller pps with UDP floods. As I am not a programmer I do not know the internals as to why, but I would assume it is due to an icmp error as your e-mail stated. I was trying to alert him that in the future he might want to look to see if massive amounts of UDP traffic is coming in when receiving that message :> On Mon, 28 Aug 2000, Alfred Perlstein wrote: > > > Sep 19 00:17:54 shell /kernel: icmp-response bandwidth limit 3491/200 pps > > * Matt Ayres <matta@unixshell.com> [000828 11:13] wrote: > > FreeBSD will also give the message below when UDP has gone over 100pps. > > Can you explain?
