There are no known bugs on the RX side in 2.6.16 that would cause this.
The few busy web servers that I have access to do not see this message
at all.
So either your web server is somehow attracting a lot of buggy TCP stacks,
or there could be a dodgy gateway in your path that is mucking with the
TCP windows.
You're right, actually this box serves http/ftp file transfers only,
it's a mirror with a large amount of downloads a day.
On a pure html/image web server that is just as busy, there are only a
few of these messages, one or two a day.
I suggest that you do a tcpdump to see what it looks like. It might turn
out that we do still have a bug on our RX side.
I gave it another look, many of the prints are repeat prints for the
same remote IPs,
BTW, this message is already under net_ratelimit so I don't see any
urgency in getting rid of it completely. If we're going down the
path of disabling it, we probably should go for something more global
rather than a sysctl that controls this one message.
I agree, however, I think it's pretty good to allow an admin to toggle
it off completely. Maybe that's all we need, really.
Thanks
