We created another dev thread about this: http://www.jboss.org/index.html?module=bb&op=viewtopic&t=159473 Basically global-max-size means the hard limit you have on the server. It' s like a memory full, and it should put everything on file instead of memory. For correct paging, you should have everything using individual addresses settings. And we will document that clearly. So, JBMUser: Basically your test made the server "full" and nothing got routed after that, what should be the expected behaviour.
