OK, that does sound like something that reducing the keepalive
interval could help with. The traditional keepalive timeout
is a couple of hours, at least on my Linux box:
$ cat /proc/sys/net/ipv4/tcp_keepalive_time
7200
but it sounds like there's something between you and the database
server that will forget connections a lot quicker than that.
