The comment here seems to indicate it is for cleanup of dead connections. Can someone enlighten me or point me to relevant doc? tcp_keepalive="YES" # Kill dead TCP connections (or NO). -- __ / ) _/_ It is a capital mistake to theorise before one has data. /--/ __ / Insensibly one begins to twist facts to suit theories, / (_/ (_<__ Instead of theories to suit facts. -- Sherlock Holmes, "A Scandal in Bohemia" Arthur W.
