------------------------------------
Summary: When socket is closed in proxy, should ping to verify its
connection status
Key: GEODE-6316
URL: https://issues.apache.org/jira/browse/GEODE-6316
Project: Geode
Issue Type: Bug
Components: client/server
Reporter: xiaojian zhou
When client's socket was closed, the server's socket.isConnected() will still
be true if there's no msg is sent to it.
So to verify if a proxy is still alive, we should ping it.
The original checking code "if (staleClientProxy.isConnected() &&
staleClientProxy.getSocket().isConnected())" was introduced in GEODE-1183.
While the idea of GEODE-1183 is still valid, this checking logic is not mature.
When a client's socket is closed, and it tried to reconnect, it could fail with
"A previous connection attempt from this client is still being processed:" and
cannot connect.
The fix is to send a PING msg to an existing proxy. If failed, the PING msg
will automatically close the proxy.
