Re: BUG #2576: tcp_keepalive doesn't work

Hi.

I found the cause of the error that tcp_keepalive doesn't work.
The cause is a specification of linux kernel.

In the specification of linux kernel, tcp_keepalive doesn't work
if the network outage occurs before receiving ACK for send() system-call.
This behavior of tcp_keepalive is reported even by LKML.

I'm confused whether tcp_keepalive problem should be solved
at the DB level.
