[jboss-jira] [JBoss JIRA] (AS7-4786) MSC controller hangs when loading an ear with multiple presistance units on a single threaded machine

Stuart Douglas commented on AS7-4786:
-------------------------------------
I suspect the root cause of this would be MSC thread pool starvation, caused by
org.jboss.as.jpa.service.PersistenceUnitServiceImpl starting in a MSC thread, instead of
doing an async start.
Can you try starting the server with -Dorg.jboss.server.bootstrap.maxThreads=30 on the
single core machine and see if this works?

Key: AS7-4786
URL: https://issues.jboss.org/browse/AS7-4786
Project: Application Server 7
Issue Type: Bug
Environment: Centos 6, single core lib-virt VM
Reporter: Wouter De Borger
Assignee: David Lloyd
Labels: hibernate, naming, race
When deploying an EAR with two persistence units on single core machines, the server
hangs.
When increasing the number of cores to two, the same server just works.
I traced the bug to the method in
org.jboss.as.naming.WritableServiceBasedNamingStore.unbind
The container attempts to register "hibernate/SessionFactory" twice.
The first time it works, the second time it hangs on the wait statement.
I suspect a race condition in the ServiceControllerImpl.
