1) The Server is already tuning off for window scaling during the 'Treason
Uncloaked' occur
bash> cat /proc/sys/net/ipv4/tcp_window_scaling
bash> 0
2) Yesterday evening I also update the latest kernel from version
2.4.21-4to the version
2.4.33 and using up2date to install all newer packages. But today currently
at 5.53am, I still can see the message in dmesg. Se below:
TCP: Treason uncloaked! Peer 211.25.132.129:63581/80 shrinks window
1866011154:1866011155. Repaired.
TCP: Treason uncloaked! Peer 211.25.132.129:63581/443 shrinks window
1866011154:1866011155. Repaired.
TCP: Treason uncloaked! Peer 202.75.46.41:7638/443 shrinks window
1073268829:1073268830. Repair
I already spend about a week to search in google regarding this 'Treason
Uncloaked' issue. All what I can see is just explaination but there is no
spesific solution. But this issue make my webserver running in high Load
Average ( over 110 ) and cpu running 100% with Idle is 0%.
Thank you.
