Major Description
The "Making sure you have enough sockets" Geode documentation section says the following about socket-lease-time (check underlined sentence):
Peer-to-peer. For peer-to-peer threads that do not share sockets, you can use the socket-lease-time to make sure that no socket sits idle for too long. When a socket that belongs to an individual thread remains unused for this time period, the system automatically returns it to the pool. The next time the thread needs a socket, it creates a new socket.
Actually, the system automatically closes the connection in the situation described instead of returning it to any pool.
