What could be the cause of JVM thread dumps that show threads waiting to lock on a monitor, but the monitors do not have corresponding locking threads?

when I issue a kill -3 command to my java program, its generates the thread dump on the console. How do I redirect this to a file?
Tks!

Our Java application starts a worker thread (using Thread.start()). Shortly thereafter it calls Thread.join() on the worker thread. The worker thread does some stuff and terminates. The first thread exits the ... |

This question is very similar to that question:
however it is more specific. I would like to dump stack trace also with local variables that are java primitives e.g. int. In ... |

I'm writing a single threaded program, which sometimes calls blocking methods (ie process.waitFor).
Can I be sure that the interrupted status of my thread is never set? Are there other conditions under ... |
Now, when the thread.start() is called, how does the JVM know to call the run() method of the class A but not its own run() method [Thread class implements Runnable.] The new thread will call the run() method of the Thread object... If you override the run() method (by extending the Thread class), then it will call your run() method. In ... |
Yes, if you System.exit(), then all threads (even native ones) will stop, because System.exit() blows away the process (in the JVMs that I know, anyway). However, your Java program generally should not System.exit() unless it really has to. When you System.exit(), all threads stop, regardless of what they were doing at the time. Also, using System.exit() makes your code unsuitable for ... |
Hi all, This is really a two part question: A) how is a thread told/forced to exit? And, b) How can I code my thread so that it exits where I want (and not where I do not want.) E.g.: public class MyThread extends Thread{ public void run(){ while (true) { //do something here doSomething(); //do something there PART I doSomthingThere_1(); ... |

hi all, was wondering whats the best way of stopping a thread without exiting the JVM. I have a java programme which spawns out a few threads in the jvm , each of these threads do different things and i need to stop one of the threads when file name already exists while the other threads continue to run : public ... |
Hi Friends, I am learning Threads & Runnable. I am wondering that when I say Thread.start(), why & how run() method get invoked and starts it's execution? Is there any logical thing behind to call run() method from JVM / from start() method? Can some one tell me how and why SUN is run() method when I say start()? Thanks regards ... |
Good day! Sometimes (about each two days) our production server falls down. But we can't understand why. There is no one record in logs and stdout. When server has falled down two days ago, I make full stack dump (kill -3). This is the link to stackdump: http://users.g.com.ua/~vitaly_b/work/stackdump2.zip I have writed tool that analyzes stackdump. I've seen that there is 5 ... |
When i stop the JVM I can see the latest value displayed, but other threads responsible for generating that value keep on running in the background and i need to stop those threads as well. Huh, how is it possible that threads keep on running when you stop the JVM? When you stop the JVM, all threads automatically stop. You need ... |
