[jboss-jira] [JBoss JIRA] Updated: (JBAS-9042) Multiple threads blocking waiting to close Pipe.in during smoke tests

Multiple threads blocking waiting to close Pipe.in during smoke tests --------------------------------------------------------------------- Key: JBAS-9042 URL: https://issues.jboss.org/browse/JBAS-9042 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: Domain Management Reporter: Brian Stansberry Assignee: Brian Stansberry Fix For: 7.0.0.Beta3 Attachments: org.jboss.as.test.embedded.demos.ejb3.StatelessBeanTestCase-output.txt I'm seeing hangs in the smoke tests where threads are all blocking in the management request handling code. Thread dump attached. One thing that stands out is the large number of threads in this state: "pool-1-thread-7" prio=5 tid=102be5800 nid=0x10f377000 in Object.wait() [10f376000] java.lang.Thread.State: WAITING (on object monitor) at java.lang.Object.wait(Native Method) - waiting on <7f5235be8> (a java.lang.Object) at java.lang.Object.wait(Object.java:485) at org.jboss.as.protocol.Pipe$1.read(Pipe.java:75) - locked <7f5235be8> (a java.lang.Object) at org.jboss.as.protocol.ConnectionImpl$MessageInputStream.close(ConnectionImpl.java:302) at org.jboss.as.protocol.StreamUtils.safeClose(StreamUtils.java:294) at org.jboss.as.protocol.mgmt.AbstractMessageHandler.handleMessage(AbstractMessageHandler.java:65) at org.jboss.as.protocol.ConnectionImpl.safeHandleMessage(ConnectionImpl.java:254) at org.jboss.as.protocol.ConnectionImpl$1$1.run(ConnectionImpl.java:213) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:680) I don't see how there would be that many concurrent requests going on; what I *suspect* is happening is those threads are handling requests from different test cases and are hanging. Eventually the pool is exhausted.
