If a network connection between jrly and jrad is broken in Jolt 1.1, the jrly's first reconnection attempt fails. Yet, subsequent attempts succeed because the jrad gets notified of the network state, and closes the connection. However, in base Jolt 1.2, the jrad doesn't get notified of the broken network connection. All attempts to reconnect to jrad fail until the jrad is recycled. In the Jolt 1.2 rolling patch, the jrly cannot reconnect to jrad until the TCP keepalive timer expires. When the TCP keepalive timer expires, JRAD closes the network connection, and frees itself to accept a new jrly connection. A customer observed that a firewall timeout caused jrly to disconnect from jrad. While this wasn't a problem in Jolt 1.1, it made his application unstable in Jolt 1.2. The customer asked for the jrad in Jolt 1.2 to work like it did in Jolt 1.1, which was more robust.
