We have had similar problems.

Someone on the list asked whether we have some NAT (Network Address
Translation) agent in between. We had...
Such NAT agents close connections when unused for some time
in order to protect their resources. The timeout of our NAT agent
was 30 min.

Our solution: send a keep alive message every 20 min.
