What happens is the chat-channel or messages (left of the screen) stops, and "no messages received" pops up on my screen (while everything is working as normal otherwise, I can move around and do stuff), as well as a small yellow symbol lower right on the screen. It starts a counting, which reaches about 50/60 before the little symbol turns red and I am kicked off the server. This happens within 5-10 minutes of playing, after everything seemingly working fine, with no lag nor other issues.

Not sure what this is, or why it happens. Everything seems to be working fine for the first while. The game performs well, although the PC gets very warm. I have wanted to put the game down, to check CP/memory usage, but the game will not let me put it down, so I haven't been able to check this.
