1. The 'all' server was experiencing OOMEs of the PermSpace variety, as opposed to the heap space variety. Heap space is used to store object instances and other garbage-collectable data items, whereas PermSpace is used to store class definitions and other 'permanent' data structures, which are not subject to garbage collection (as far as I am aware). These were visible in the log as: 18:23:08,027 ERROR [STDERR] Exception in thread "JBoss System Threads(1)-108" 18:23:08,027 WARN [RunnableTaskWrapper] Unhandled throwable for runnable: org.jnp.server.Main$BootstrapRequestHandler@8aba19 java.lang.OutOfMemoryError: PermGen space 2. The fact that servers controlled with server:start and server:stop do not shutdown correctly seems to be due to memory problems: I ran the testsuite with the JVM memory settings -Xms256m -Xmx256m -XX:MaxPermSize=128m -XX:PermSize=128m and the server shutdown problems (as well as the OOMEs) disappeared.
