Connections are closing up?

[Eliezer Croitoru <eliezer@xxxxxxxxxxxx>]

I am using clients and it seems like the connection is breaking from 
unknown reason.
I was thinking of maybe the blame is the: client_idle_pconn_timeout.
it's a CONNECT connection and I can dig up the logs to see what happens 
but it seems rather weird.
Are there any settings in the linux kernel like sysctl to turn on keep 
alive for all tcp connections?
