Dario, we are seeing several instances of the following in our logs:

20-Jan-12 14:07:52,695|INFO |LightstreamerLogger.requests |FOR PUMPS PARKING DESTROYER|Closed session Se6150bc443e107beT5831853 with internal cause code: 38

This is similar to the issue above. Can you clarify that this means the LS server thinks the client disconnected from it? And therefore, the LS server will stop sending updates to the client.

What are typical root causes when seeing a high number of these?
