  If instead you just go "I dunno, I'll post it to the list so you guys will tell me what's up", then no... we won't read it.  If you can't be bothered to read it, then why should we?

  And this isn't rocket surgery.  If the value of Acct-Status-Type doesn't match "stop", then read the debug output to see what's in the packet.  It's what I said to do.  Why not do that?

  FreeRADIUS gets packets from the NAS.  When the NAS decides to send them.  The contents of the packets are controlled by the NAS.

 So your question is really "when does the NAS send session timeouts, and what's in those packets?"

  The answer is "we don't know, and we don't know".

  There are thousands of NAS vendors, each of whom has thousands of products, each of which has dozens of firmware revisions.  You have to read the NAS documentation and the debug output to see what the NAS sends, and when.
