reply | permalink Nick Klauer Yeah, for now, with Leiningen 1.6.2's newly released update, they changed how they handle their own leiningen classpath (they used to reference .classpath, now .lein-classpath), so I think the owner will reveal who is causing the lock > contention that makes the WorkerPool create so many Workers. I use Helios. OutOfMemoryError: unable to create new native thread – what is it? have a peek at these guys

The application does continuous background processing, so has very little idle time. All Rights Reserved. I don't have an exact count, but we are probably looking at maybe 300 threads for the user total). Plus, while "old news", I have found some issues with Xvfb and memory leaks.

Out Of Memory Error Unable To Create New Native Thread

Requested array size exceeds VM limit What is causing it? Windows resource monitor says that the process has over 18000 threads and when I hit Ctrl-break in the eclipse/java console window the thread dumps have the same thread death related join Download the whole handbook as a 28-page PDF or e-book java.lang.OutOfMemoryError: Unable to create new native thread Java applications are multi-threaded by nature. So if my app has about 40 threads, we are looking at 20 MB of stack. 500MB heap.

The next step will be to look at the possible problem patterns and determine which one is applicable for your problem case. My guess is, though, it's only "hit" in testing ... With the patch, there were a few score of Identifier Update Job and a few score of Identifier Update UI Job messages printed. Unable To Create New Native Thread Linux A safer alternative would be to avoid the tons of jobs and just pack all the updates into a single UIJob.

reply | permalink Sean Corfield FWIW, here's the workflow I use with CCW and Leiningen: * create the project normally with Leiningen: lein new my-project * get the initial deps in Comment 47 David Williams 2015-11-25 12:26:21 EST I have put "backport" in the whiteboard field meaning to consider as a candidate to backport to 4.5.2 release. For example, see http://blog.jeffterrace.com/2012/07/xvfb-memory-leak-workaround.html Anyone remember a good command line method (or, Java, or Ant :) to determine which version of GTK is "seen" and especially if there might be "mixed" Comment 21 David Williams 2015-11-15 17:42:10 EST (In reply to David Williams from comment #19) > I have not been able to reproduce this memory/thread problem in the IDE.

Java Out Of Memory Error Unable To Create New Native Thread

Problem pattern #1 – C-Heap depletion (32-bit JVM) From my experience, OutOfMemoryError: unable to create new native thread is quite common for 32-bit JVM processes. I think the owner will reveal who is causing the lock contention that makes the WorkerPool create so many Workers.

So as a result, your threads have only about 256Mb for stacks, which is maximum 64 threads (256/4m). check my blog We can clearly see this logic from the OpenJDK 1.6 and 1.7 implementations as per below: Unfortunately at this point you won’t get more detail than this error, with no indication of

Comment 6 Henrik Dohlmann 2009-08-04 07:00:15 EDT While the Debug View hanged, i tried to start a new instance.

Investigations around GC code or at the point where threads are already exhausted are not going to help.

Any idea? Also, I have learned from watching several runs, when to hit "pause" in the debugger after it has a hundred workers or so but before it gets to that 200 limit. What's the last character in a file? Java.lang.outofmemoryerror: Unable To Create New Native Thread Windows Somtimes I get a "Problem Occured" dialog with the text "'process model delta' has encountered a problem", "An internal error has occured".

And further, all those calls were from the two methods I mentioned earlier. That NullPointerException is occurring in a place that suggests that the project in question has some configuration that CCW expects. reply | permalink Nick Klauer I've fiddled with alot of settings, and the result tends to switch between an outright OutOfMemory exception that kills Eclipse entirely, and just hanging the run news In Skyrim, is it possible to upgrade a weapon/armor twice?

Also +1 to Markus patch in this case.

Please note that this problem can also manifest itself as a full JVM crash (as per below sample) when running out of OS virtual memory or swap space on Solaris. # Normally this is never any type of problem, However in Java based applications this can cause your system to run into system limits!
