I have indeed commented in the TCPKeepAlive and tweaked the value of
tcp_keepalive_intvl to 300 which no such luck unfortunately, What I can't
understand is it can't be due to the networking as other people are having
no problems but I am the only one using Ubuntu as my OS, it also can't be
due to it timing out as 9 times out of 10 im actually using the connection!
Its the first time I have ever experienced this sort of problem though
