Hi Robin, I found this in the jrun docs under the heading 'session replication', which seems to suggest that the sessions are only replicated after each request.
http://livedocs.macromedia.com/jrun/4/JRun_Service_Pack_1_Guide/4relnotes5.htm Session replication The following issues related to session replication are not fully explained in the JRun 4 documentation: * Session replication only happens at the end of a request when setAttribute or removeAttribute is called on the current session. The only time you must be aware of this feature is when making a change to an existing attribute. This is a bit of a problem when doing maintenance. If I restart server A, to ensure that I'm not going to drop any sessions I have to wait for the session timeout length before I restart server B.

I'd assume that the cluster buddy who was restarting would pick up the replicated session state from the other buddies before it started accepting requests, otherwise the whole replication feature would be highly impractical (you'd always have to start and stop the entire cluster at the same time). That said, I'm not sure - I've pinged Mark Blair to see if he can ask Brandon Purcell for us.
