    Default Java Application After Power Failure

    I have a java application that is being run as a Linux daemon process. It gets started on boot via an init script, and gets shutdown with the same script at shutdown. All works fine.... During unit testing, I ran it against a power failure condition, specifically, pulling the plug from the box.

    When the system boots up, I can see that the program is "running" and it has an attached PID, but if I probe the jvm for that PID using jconsole, none of my java classes are loaded nor are any of my threads running. From all I can tell, there is just a "ghost" program running. In order to clear it, I have to kill the PID and restart.

    Any idea what is going on? Any idea as to how to resolve so that the application successfully starts after a power failure?

    Default Re: Java Application After Power Failure

    Have you got any logs for your process?
    If not then I suggest trying to set some up, especially on the start up side, so you can at least see if it is doing anything.
    Please do not ask for code as refusal often offends.
