Exception during client disconnection: Null

I've been running my server for quite a while this is the first real error I've seen in my logs. I'm using the latest Smartfox 1.6.5 and Linux.

Are you doing something in your extension after disconnection?

Unless you are getting many of those in a row I wouldn't worry about it.

No its the first time I've seen it. But there is always some little bits of warnings and errors every once in a while. I guess its the nature of a multiplayer system where anything can happen at anytime.

I have similar problems. On SFS 1.6.6 I get the following errors quite often:

Code: Select all

--> MyZoneExtension.java:3841

Code: Select all

if (kickUser != null) {
 eHelper.disconnectUser(kickUser);
}

I would guess, that in 1 out of 10 cases in MyZoneExtension, this error occurs.

Is there anything, I can check in advance, to prevent this error?

No and there's not much to worry about it
Anyways this will be addressed in the next update, it's already in the todo list

Thanks for reporting
