This happens about twice every day. I'll try to post something in the chatbox and it gives me a "Posting message already" or something error. I'm not sure of the exact wording, I'll write it down once I see it again, but it doesn't let me type anything in for like 10 minutes. I guess it just times out and doesn't refresh fast enough.

Here's that red text, WW:
