So far so good? I've been checking the reply count and haven't seen a note from anybody that they had a lock or no-show while posting.
I got a follow-up e-mail from the hosting tech support today -- they were able to find a stat tracking program that appeared to be locking things up. We'll see if that helps keep the server load down -- which is what appears to be the primary cause of the board getting show and locking when users submit posts.
However, I don't know that it is the reason behind the reply count problem that we saw before.
