Hi All On a production apache (apache2-2.2.0) Linux servers (SUSE 10 x86_64), I 've noticed few errors in message log file.
Jan 29 21:29:30 apache1 kernel: TCP: Treason uncloaked! Peer 87.181.xxx.xxx:4780/80 shrinks window 1196468641:1196482332. Repaired. Jan 29 21:29:54 apache1 kernel: TCP: Treason uncloaked!
