    Hey Adam,

    You should ping Bryan Cantrill. :)

    Hi Adam,

    Need to check if you can help to dissect this.

    Need help on a bug in an old Java version:
    http://bugs.java.com/view_bug.do?bug_id=6970542

    My application code that utilises that buggy JRE is invoked many times a day, but I find it strange that my system was hit by performance issues only 4 months after commissioning. By right, we should have been hit on day one.

    Additional posts on this issue:
    http://stackoverflow.com/questions/7321233/very-slow-java-startup-in-solaris-10

    Very similar to what was shared, on 2 other similar setups running the exact application, we don’t face this issue.

    On the problem server, running “truss java -version”, there’s a long wait at:
    open64(“/dev/dtrace/helper”, O_RDWR) = 3

    On the other 2 servers, “truss java -version” runs all the way through without halting.

    What is causing the bug to appear?

    Thanks!
