Removing client from ip:66.191.88.178 port:1311


This happens everytime someone tries to log on to my server. Strangely enough it does the exact same thing when i had it setup on my windoz box. Hardware problem? bog? Any ideas?

They get to the char select and just b4 it appears or shorrtly after, those disconnect msgs show up on my end.
