[jboss-dev-forums] [Design of JBoss internal QA (Test Suite)] - Re: Testsuite runs failing due to server failed startups/tim

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 at 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.
