Hi
Sorry for my bad english.
I use SmartFox with Unity. But since I use SmartFox, Unity freeze for a while. But there is not a logic
behind. Sometimes it freeze by press the play button or when I stop the game or when I
change a script and save it, while runtime.
But when it freezes Unity, I must wait ~2 minutes and it works again.
Somtimes comes after the freeze a NullReference Exception, but not often.
It’s make me nervous 
Can somebody help me PLEASE?
thx 
Are you using the 2x version of SmartFox? Is this happening in the editor only?
It sounds like the Smartfox server session might be timing out after a few minutes and releasing the tcp connection.
Edit/Project Settings/Player → Run in background maybe ?
I use SmartFox Server 1.6.6.
It works now better, but I dont’t know the reason ^^
I take a look to the multiplayer Island Demo and code my programm a bit cleaner.
Thx for help. 
Hey I had a similar issue, make sure your using the queue mode of smartfox server otherwise your opening unity-unfriendly threads
