Timeout for activity check warnings, expressed in milliseconds. If no data is being received on the stream connection and a keepalive message is late for this time, then a notification is issued to the IConnectionListener that the connection is stalled. 

After the notification, if some data or keepalive is received before ProbeTimeoutMillis elapses, then a notification is issued to the IConnectionListener that the activity is normal again; otherwise the connection is forcibly closed. 

The default setting is 2000 (2 seconds).
