can't stay on server for more then 10 seconds

[kariboe]

Hi,
When my friend joins the server, his client shuts down after approximately 10 seconds.
The weird thing is that he is the only one with this problem, all the othe members can join and play without problems.

This are the server logs when his client shuts down:
