Connection never recovered sometimes [Java]

[romainmoreau]

Hello,

I'm using a LSProxy to receive various updates using the latest client (2.5.2 build 1110).

The LSProxy is initialized in a pretty straightforward way :

ProxyInfo proxyInfo = new ProxyInfo();
proxyInfo.onFailedConnectionRetry = true;
proxyInfo.connectionRetryTimeoutMillis = 30000;

LSProxy lsProxy = new LSProxy(proxyInfo, this, this);

ConnectionInfo connectionInfo = new ConnectionInfo();
connectionInfo.pushServerUrl = "...";
connectionInfo.user = "...";
connectionInfo.password = "...";

lsProxy.startPushConnection(connectionInfo);

It works great most of time but sometimes I get this behaviour :

The "Connecting, Disconnected, Reconnection attempt failure, Retry after reconnection failure" pattern keeps repeating itself, the connection is never recovered.

What could be the cause of such kind of problem ?

Thanks.
