Hi,

we use http&socket  
and set  
SocketFactory.rmiServerFactory: to com.servoy.j2db.server.rmi.tunnel.ServerTunnelRMISocketFactoryFactory

SocketFactory.useTwoWaySocket: true  
SocketFactory.compress: true  
SocketFactory.useSSL : false

But still I frequently see following errors in the log :

This is not necessarily a problem, it’s just the server that wasn’t able to connect to a client for a databroadcast, probably that client was put to sleep without closing servoy first or the client network went down for a while. Check out with the user if he experienced any problems around the legged time.
