A stale session in radacct could happen simply due to the loss of a udp packet with the accounting information in it. RADIUS is totally stateless and has no reliable mechanism for deciding if a user is present or not.
If simultaneous use relies entirely upon the contents of radacct, it's very vulnerable to packet loss and also, if you're using multiple radius servers for authentication/authorization and for accounting, you may not have access to all the logs anyway. I was under the impression (possibly falsely) that simultaneous use relied upon the presence of snmp to function properly (I've certainly seen warnings when compiling that snmp isn't present so simultaneous use may not function correctly).
