Failed to reply to threads
The bad thing here is that I don't we have seen any single thread that have locked up and later come to life. They seem to be permanently dead.
From the forum visitor's perspective, there is no way to inform the OP of a locked thread, that he/she has to re-create a new thread to raise his/her question.
That's because it's a situation that shouldn't happen!!
