SmartFoxServer 1.6.18

I updated the smartFox and keeps giving this warning, is it normal or is it a problem?

[ WARNING ][ SmartFoxServer.dispatchEvent ] Unknown event type: , Disconnecting:
java.nio.channels.SocketChannel[connected local=/***.56.85.**2:5588 remote=/189
.54.218.52:3920]

Hi,
no there's no relation with the update. The error simply indicates that a client is sending messages that contain unknown commands.
It could be that these clients are web bots probing online services, or it could be some kind of spam attack if the error occurs very often.

Cheers

This is happening and the connection closes, the clients don't connect anymore.

The solution is denying access to clients sending garbage requests via firewall rules.
