Here the situation:

- take any jboss version
- start it with the "all" configuration
- go to the jmx-console
- go on the "jboss.system:service=ServiceController" mbean
- launch the "stop" operation with the arg = "jboss:service=DefaultPartition"
you should see the stop operation complete on the server console

then
- go back to the mbean
- launch the "start" operation with the same argument

you should see the error message in the console:

ERROR [org.jgroups.stack.ProtocolStack] no down protocol available !

any ideas?

Thanks, L.
