Why does java service wrapper restarts only 5 times?

Hi, i have a problem in restarting my wrapper on demand.
I have a server and there this wrapper is running. The wrapper provides a service. This service is should be restarted after each call, because of avoiding problems with a memory or resource leak.
In my application i use WrapperManager.restart() of wrapper.jar from http://wrapper.tanukisoftware.org/.
I know that i can set the property wrapper.max_failed_invocations more than 5. But i want to restart the service every time after calling it. What can i do?
The log output is
STATUS | wrapper | JVM requested a restart.
FATAL | wrapper | There were 5 failed launches in a row, each lasting less than 300 seconds. Giving up.
FATAL | wrapper | There may be a configuration problem: please check the logs.
STATUS | wrapper | <-- Wrapper Stopped

Hmm, 159 Watt diff, that's interesting, can't picture Hard Drives using that much, can you disconnect one devie at a time to test it's not them?

  • JNI  --  Windows Service (Java Service Wrapper)  --  Winamp

    Hi!
    I'm developing an application to control Winamp player and this application is supposed to run as a Windows Service (via Java Service Wrapper). Winamp is
    handled via JNI (c library dll).
    The thing is:
    When I start the application as a service, my application tries to control Winamp (eg play, pause) but it doesn't work. I can see (prints) that my application is working but all the calls of the dll that interacts with Winamp don't answer. Instead, when I stop the service, I can see finaly all the prints (I introduced in the dll play, pause functions).
    Can anybody give a hand? It seems that the JNI is not working properly (in my humble opinion).
    Thanks for your attention.
    Best Regards
    Nuno

    In my java application:
    System.out.println("Before play!");
    play( ); //Native method...
    System.out.println("After play!");
    sleep(10*1000);
    System.out.println("Before pause!");
    pause ( ); //Native method...
    System.out.println("After pause!");
    In c file (dll lib):
    JNIEXPORT void JNICALL Java_WinampController_play
    (JNIEnv *env, jobject obj) {
              printf("-> cpp - Play \n");
    initWinampHandle();
    if (hwnd_winamp != NULL) {
    SendMessageA(hwnd_winamp, WM_COMMAND, WA_PLAY,
    WA_NOTHING);
              printf("<- cpp - Play \n");
    JNIEXPORT void JNICALL Java_WinampController_pause
    (JNIEnv *env, jobject obj) {
              printf("-> cpp - Pause \n");
    initWinampHandle();
    if (hwnd_winamp != NULL) {
    SendMessageA(hwnd_winamp, WM_COMMAND, WA_PAUSE,
    WA_NOTHING);
              printf("<- cpp - Pause \n");
    Result... (log file)
    Before play!
    After play!
    Before pause!
    After pause!
    And only after I stop the service, the cpp printf appear... :(
    -> cpp - Play
    <- cpp - Play
    -> cpp - Pause
    <- cpp - Pause
    Thanks

  • Rmid and Java Service Wrapper

    I attempted to run RMID by specifying the 'main' class to Java Service Wrapper but ran into trouble with permissions. Even a security policy granting all permissions wasn't sufficient.
    Has anyone succeeding in running RMID this way? Or any other way of running it properly as a Windows service (SRVANY doesn't count as it doesn't shutdown RMID cleanly).
    When asked to shutdown the service, SRVANY abruptly terminates RMID. This means that any 'child' JVM's remain rather than being shutdown. In addition, on Vista, it often results in an IPv6 port 1098 persisting and blocking a subsequent attempt to restart the service.

    The problem was Java permissions not operating system permissions. I tested it under my own account.
    Have you succeeded in getting rmid running under Java Service Wrapper?I have many apps in production using the Java Service Wrapper but none with rmid, sorry.
    You said that you have adjusted the Java permissions.
    Did you follow the advice in the FAQ ?

  • When importing RAW files in Photoshop why does camera raw 8.6 only import 1 size?

    When importing RAW files in Photoshop why does camera raw 8.6 only import 1 size from canon 5d mark iii, in older versions I used to be able to import the files as larger images. It use to have a number of options for the images size. The option now is smaller than the maximum size used to be.

    You know what - I'm sorry
    I'd had a crazy long all-nighter session sorting out images for a client, then decided - when I should have simply gone to bed - to set up the new photoshop. At the very start I made a silly mistake, tried to sort it out then decided to call it a day, responding to your remarks with the problem still in my head but feeling more and more tired.
    Responded again to your comment earlier with the problem still in my head but not in front of me on the screen - however with a fresh head I just turned it all on, opened up PS and today could instantly see what was going on - Oops!

    Just in case I wasn't clear in my last line "just Click-drag on the Tail of your .PSD to set the desired Duration," once you have Imported your .PSD (as Footage), just drag it to the Timeline, Click-drag on the right-hand margin (the Tail) and stretch out its Duration, as is required.
    Now, if you Imported as a Sequence, open that Sequence's Timeline, and do the same.
    I normally will set my Edit>Preferences>Still Duration to about what I think will be applicable, do my Import, and then with the Info Panel handy, just alter the Duration to suit.
    Good luck,

  • Why does Java have such a large footprint?

    I've been curious about this topic for a while, but I haven't ever looked into this to any depth. I also posted this to stackoverflow but haven't gotten any solid responses so far:
    http://stackoverflow.com/questions/1107991/why-does-java-have-such-a-large-footprint
    Java - or at least Sun's Hotspot JVM - has long had a reputation for having a very large memory footprint. What exactly is it about the JVM that gives it this reputation? I'd be interested in a detailed breakdown: how much memory goes to the runtime? (The JIT? The GC/memory management? The classloader?) Anything related to "auxiliary" APIs like JNI/JVMTI? The standard libraries? (Which parts get how much?) Any other major components?
    I realize that this may not be straightforward to answer without a concrete application plus VM configuration, so just to narrow things down at least somewhat: I'm primarily interested in default/typical VM configurations, and in a baseline console "Hello world" app as well as any real-world desktop or server app. (I'm suspecting that a substantial part of the JVM's footprint is largely independent of the app itself, and it is in this part that I'd like to zoom in, ideally.)
    I have a couple of other closely related questions:
    Other similar technology, such as .NET/mono, don't exhibit nearly the same footprint. Why is this the case?
    I've read somewhere on the intarwebs that a large portion of the footprint is due simply to the size of the standard libraries. If this is the case, then why is so much of the standard libraries being loaded up front?
    Are there any efforts (JSRs, whatever) to tame the memory footprint? The closest thing I've come across is a project to reduce the on-disk footprint of the JVM [1] and to modularize the standard library [2].
    I'm sure that the footprint has varied over the past decade or so with every new version of Java. Are there any specific numbers/charts chronicling precisely how the JVM's footprint has changed?

    Presumably versus some other VM. I would suppose the fact that much of the VM is written in java has something to do with it.

    Not sure I agree with that. What size do you see with a .Net app that uses 3.0/3.5?
    I've read somewhere on the intarwebs that a large portion of the footprint is due simply to the size of the standard libraries. If this is the case, then why is so much of the standard libraries being loaded up front?
    Good question. There is a feature that allows multiple VMs to use the same memory footprint version of the loaded libraries. That is a new feature and it isn't clear to me if it covers the entire API. I do not know if that is dynamically built.

  • Why does the keyboard come up a second time on the ipad

    Why does the keyboard come up a second time on the ipad

    Try these basic things and see if the keyboard goes away for good.
    Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
    Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
    Quit the Kindle App and restart. Go to the home screen first by tapping the home button. Quit/close open apps by e tapping the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus (-) sign in the upper left corner to close the apps. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
