I'm pretty sure this means that the client failed to create a child thread for netty. Anyways, sorry if this is a duplicate, but I thought I'd report it as I didn't see any other reports related to this. Also, this error occurs when attempting to join an external server:

Reboot appeared to have fixed this. I should've tried that before reporting it. Sorry for that!
