Increasing lag and disconnection in server client arch. written with LLAPI

Unity Engine
1

When clients connects to the server, server ask them their position and send the other clients position information Ex: “ASKPOSITION|3|P:3:4:5|2|P:2:6:7”.

Clients answer that message with their position and place the recived information.

But after a while clients disconnect server. I think, if is there a buffer to keep reciving packages that might be full. But I’m not sure.

Additionaliy, is there any source to learn LLAPI ? like book, video list, web site, etc.

I suppose that You do not read what you send, or send faster than read. For demo make search please, for example this post NetworkTransport game example or there is sample echo example somewhere here
