Strange msg in system log this morning

[dmxrob]

Has anyone ran into this one before?

Apr 2 09:57:25 pride1 kernel: TCP: Treason uncloaked! Peer 24.69.255.242:22975/80
shrinks window 3971435208:3971448060. Repaired.


A Google search points to the TCP stack, but I'm still investigating.

I think this has the best (and simplest!) explanation:

It is a fairly common error caused by certain TCP stacks that do strange things. It is not malicious and the only reason you are seeing it is the TCP debugging is turned on. There is probably something in sysctl to turn it off.
