All, My apologize if this post is OT. I typed command "dmesg" and found many messages below in my Squid machine. TCP: Treason uncloaked! Peer 202.108.67.134:1099/8080 shrinks window 3327054514:3327055323. Repaired. TCP: Treason uncloaked! Peer 202.108.67.134:1552/8080 shrinks window 3447726284:3447727816. Repaired. Would you tell me what is the meaning of those lines? Is it a serious issue? Thx & Rgds, Awie
