booted to login screen

[Magifyre]

I've found that when I relog between characters a few times in a row, I will eventually be booted out to the login screen immediately after selecting a character to enter world. When I log back in, and try to enter the world, I'm told I have an active character, so the login worked, but immediately disconnected me. If I wait, and then re-enter the world once my character has disappeared, I get a UI error, and the game closes. Once I reopen the game, everything works fine. Is this normal, or something that can be corrected?
