[JIRA] Created: (HUDSON-6654) Hudson hangs on "please wait" page (DNSMultiCast?)

Hudson issues mailing list
Hudson hangs on "please wait" page (DNSMultiCast?)
--------------------------------------------------

                 Key: HUDSON-6654
                 URL: http://issues.hudson-ci.org/browse/HUDSON-6654
             Project: Hudson
          Issue Type: Bug
          Components: infrastructure
    Affects Versions: current
            Reporter: nhb
             Fix For: current


After updating to the latest version (1.359), Hudson throw InvalidClassVersionErrors. So I updated Java from version 1.5 to 6. While these errors do not exist anymore, Hudson is still not loaded completely but only shows the "Hudson is starting, please wait" page in the web browser.

There are some errors in the attached log but I think they are not related.

A thread dump, however, show this stacktrace:

"hudson initialization thread" prio=10 tid=0x0a3a2800 nid=0x1bbc in Object.wait() [0xb4162000]
   java.lang.Thread.State: WAITING (on object monitor)
        at java.lang.Object.wait(Native Method)
        - waiting on <0x82e65d20> (a javax.jmdns.impl.ServiceInfoImpl)
        at java.lang.Object.wait(Object.java:485)
        at javax.jmdns.impl.JmDNSImpl.registerService(JmDNSImpl.java:723)
        - locked <0x82e65d20> (a javax.jmdns.impl.ServiceInfoImpl)

        at hudson.WebAppMain$2.run(WebAppMain.java:222)


Hudson is running as a non root user in a choot environment on Ubuntu 9.10

---------------------------------

Can you run attach dumps from all the threads, not just that one, so that we can see what the owner of the lock is doing?

[JIRA] Updated: (HUDSON-6654) Hudson hangs on "please wait" page (DNSMultiCast?)

nhb updated HUDSON-6654:
------------------------

    Attachment: stack.txt

Hi,

I attached complete stack trace. As far as I understand the stacktrace, the init thread is not "waiting to lock" a monitor hold by another thread but waiting on a lock for someone to call notify.

Is there a way to prevent hudson from trying to register the DNS entry?
