Hi Kevin,

From the logs we noticed that the issue starts after 2 restarts of the server executed at 23:27 and 23:35 on 21 February.
Before these events, all day long, the server seems to run regularly, and the relationship between connections and sessions remains within acceptable limits.

Soon after the restarts, indeed, the connections count begins to be very high compared to the number of sessions, but only about 10 minutes after the second restart that this bursts exceeding 1000 and continuing to grow.
Also the logs starts to show exceptions like this:
Code:
	21-Feb-15 23:58:59,316|ERROR|LightstreamerLogger.connections  | Lightstreamer HTTPS Server|Accept error on socket Lightstreamer HTTPS Server:
		java.net.SocketException: Invalid argument
		...
that are really strange and suggest a heavy problem with the network.

Could you confirm that the restarts of the server was something planned or have been performed as a result of a problem?
The first resart takes a very long time, in the meantime have been carried out some updates or changes to the systems or network?
