I was going to post that crazy error message too, just to prove to myself that I actually saw it. Here it is again!
Mistake! There was an attempt of an automatic insert of the message in a forum. Your message is sent to hell. Try still times who knows - can it will turn out? Still probably, that you too long wrote the message - then pass to page back, copy the text, update page, insert the copied text and press button "Send".
That is a pretty incomprehensible message though. Perhaps someone ought to go into the messageboard setup and change it to say something like:
"Hey, you waited too long and your post is lost. Sorry, Charlie!"
