Popular problem.
 

Followed the eqemu instructions for the client ( using eqemu servers ) word for word , no if ands or buts about it . I log on fine, i get to the character select screen. I choose a character to modify for creation ( guild wars server + FH server i've tried both ) and at a random time during me changing stats and such. Eq d/c's and goes back to the server selection screen.

If any extra info is needed to resolve this drop a line i'll have a reply with it =)

You could be getting flooded with data if your datarate in the datarate.txt file is set too high.
