[Spread-users] java: reconnect to spread deamon

[Ryan Caudy]

You're trying to reuse a private name, after the connection dropped
unexpectedly, correct?
Spread will free it up and allow re-use, but only once it realizes the
connection is down.

I think you might be able to stimulate it to notice sooner by
triggering a write to the downed connection's socket.

One mechanism to accomplish the above would be to have all of your
newly created connections join a single group "heartbeat", and
periodically send messages to that group, on the order of once a
second.
