Is it possible to get a thread dump of a Java Web Start application? And if so, how? It would be nice if there were a simple solution, which would enable a non-developer (customer) to create a thread dump. Alternatively, is it possible to create a thread dump programmatically? In the Java Web Start Console I can get a list of threads b...
I like to generate a thread dump programmatically. I've learned that there a basically two ways to do it: Use the "Java Virtual Machine Tool Interface" JVM-TI Use the higher abstracted "Java Debugger Interface" JDI For the JVM-TI I was able to find some useful information, but I would have to write a JNI-DLL which, at least for the m...
Hi I used to generate thread dumps by running kill -quit and I would get them in a log file where my server logs were there. When the file grew too large I removed it using rm and created a new file of the same name. Now when I use kill -quit to take the thread dumps, nothing gets copied in the log file - its empty. Can anyone help? ...
I am a neophyte at Weblogic troubleshooting. We have an issue on our production environment. I cannot access the ennvironment directly (our hosting people will do that, but it's some hours until I can ask them things). I have a thread dump from the time the issue was evident on production. I can look through the dump and deduce some th...
How can I show the threads (stacktraces) in a hanging application that run with MONO? I know that I can do it in .NET with the Managed Stack Explorer (MSE). Because the application hang only with MONO that I need to do it with MONO. Or there are any other ideas how I can find the place of hanging? ...
I have a production web application (Struts, iBatis, Hibernate) that runs in Tomcat that would hang while serving requests after 6 - 7 days of running but would run fine again after doing a thread dump. I have a hard time figuring out why that is the case. I was just wondering whether anyone else has ever encountered something similar....
I got a thread dump of one of my processes. It has a bunch of these threads. I guess they are keeping a bunch of memory so I am getting OOM. "Thread-8264" prio=6 tid=0x4c94ac00 nid=0xf3c runnable [0x4fe7f000] java.lang.Thread.State: RUNNABLE at java.util.zip.Inflater.inflateBytes(Native Method) at java.util.zip.Inflater.inf...
We have a java process running as a daemon (under jsvc). Every several days it just stops doing any work; output to the logfile stops (it is pretty verbose, on 5-minute intervals) and it consumes no CPU or IO. There are no exceptions logged in the logfile nor in syserr or sysout. The last log statement is just prior to a db commit bei...
When I am trying to use JStack to get the thread dump of my frozen application, one of the threads gives me this result: Thread 27560: (state = IN_NATIVE) - org.eclipse.swt.internal.gtk.OS._gtk_adjustment_changed(int) @bci=0 (Compiled frame; information may be imprecise) Error occurred during stack walking: java.lang.NullPointerExcepti...
With JRockit, you can get the full list of threads by any means, and all of these means include information about the Garbage Collection Thread(s): 1) Asking the Thread class for the information: Thread.getAllStackTraces(); 2) Using ThreadGroup to get that information: ThreadGroup root = Thread.currentThread().getThreadGroup(); whil...
