Jstack could help to see what all those 2000 threads are doing and probably could help to identify the root cause. http://strongboxlinux.com/unable-to/eclipse-error-unable-to-create-the-selected-preference-page.php

On the production machine, all these roles and responsibilities are more professionally divided between different "users". This happens 5 or so times a day. Any idea? The fix was to get the 3rd party library to close the DeflaterOutputStream. http://stackoverflow.com/questions/6754628/eclipse-crashes-with-unable-to-create-new-native-thread-any-ideas-my-setti

Out Of Memory Error Unable To Create New Native Thread

Normally this is never any type of problem, However in Java based applications this can cause your system to run into system limits! But, the problem does not occur on the production machine where we normally run the tests. Set the limit to 150 and let it run over lunch (or whenever you can survive 1h without that machine;-). and perhaps feature patch (after one more build), if anyone wants to "try it out".

The number of processes running can be counted with a ps output: $ ps -elf | wc -l 220 This number however does not consider the threads which can be spawned Worse yet, it varies by Operating System and (I am guessing) VM! readRegistry(boolean) updateListeners(boolean, Map, Set, Set) I *never* saw it called from getUpdateJob.

Java Out Of Memory Error Unable To Create New Native Thread

Comment 2 David Williams 2015-10-18 22:33:18 EDT I do see, with MANIFEST Editor open that the little "heap indicator" (in Eclipse) does "cycle" from about 200M of 1000M up to around his explanation though, of course, this was only the performance tests. Out Of Memory Error Unable To Create New Native Thread More precisely, it means that the JVM native code was unable to create a new “native” thread from the OS (Solaris, Linux, MAC, Windows...). Unable To Create New Native Thread Outofmemoryerror My latest "theory" is that it may be related to the version of GTK that is "detected" while running the performance tests in their "test environment".

I suspect this is a relatively 'minor' bug (i.e. http://strongboxlinux.com/unable-to/eclipse-error-unable-to-locate-the-javac-compiler-in.php That project contains disabled activities, which block this code path. The next step will be to look at the possible problem patterns and determine which one is applicable for your problem case. I am currently unable to debug. Unable To Create New Native Thread Ulimit

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. So in doubt just check how many Eclipse instances you run with "jps -l". First of all check the default Thread Stack size which is dependent on your Operating System: $ java -XX:+PrintFlagsFinal -version | grep ThreadStackSize intx ThreadStackSize = 1024 {pd product} As you this contact form Comment 32 Jason 2010-05-11 19:34:42 EDT Understood.

Comment 33 Lars Vogel 2015-11-18 14:16:10 EST +1 for trying Davids solution and reverting it in case we find to (hard to fix) problems. Java.lang.outofmemoryerror Unable To Create Native Thread Is it a fallacy, and if so which, to believe we are special because our existence on Earth seems improbable? Comment 3 Henrik Dohlmann 2009-08-03 02:52:59 EDT Created attachment 143238 [details] Frozen Debug view The list of running threads is expanded alot, but no names show up and then it freezes

Let’s start with a basic explanation.

Situations where it's called in other threads can be found in the > above bug query. As far as I know, could be related to the version of the Linux Kernel I am running (4.1.8), or something odd like that. Each thread allocated needs a chunk of stack and heap memory, so I'm sure if you create enough threads you eventually run out of memory. Java.lang.outofmemoryerror: Unable To Create New Native Thread Windows With this in hand, we may be able to figure out what is happening using a tool like Eclipse Mat.

That way it gets going before the memory is exhausted. –edharned Nov 14 '13 at 14:56 | show 12 more comments 2 Answers 2 active oldest votes up vote 2 down 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. Comment 5 Henrik Dohlmann 2009-08-04 04:20:37 EDT Created attachment 143368 [details] Frozen Debug view with GC threads Today I managed to get the Debug View to show all the threads instead http://strongboxlinux.com/unable-to/eclipse-http-error-500-unable-to-compile-class-for-jsp.php So, there are alot of entries with the name: * Thread [garbage collected] (Running).

Here's an example: /opt/eclipse/eclipse -ws gtk -data /home/lprefontaine/workspaces/higiebus -vmargs XX:MaxPermSize:512m -Xmx1024m -Xms1024m If you are using the defaults, it's possible that the JVM does not have enough memory. According to that reference above: https://plumbr.eu/outofmemoryerror/unable-to-create-new-native-thread My troubles begin right when it says it should, for Ubuntu 12.04 ... When that happens I cannot connect with JConsole, but with SysInternal's Process Explorer I can see that the javaw.exe has an excessive amount of threads called "msvcr71.dll!_endthreadex+0x31". Comment 13 David Williams 2015-11-03 22:12:36 EST I think the test responsible, or, related, to this issue is GenerateIdentifiersTest.

Here is the additional info you asked for, exception stack trace: java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start0(Native Method) at java.lang.Thread.start(Thread.java:640) at org.eclipse.jface.text.contentassist.ContentAssistant$AutoAssistListener.start(ContentAssistant.java:263) at org.eclipse.jface.text.contentassist.ContentAssistant$AutoAssistListener.keyPressed(ContentAssistant.java:345) at com.adobe.flexide.editorcore.contentassist.FlexContentAssistant$FlexAutoAssistListener.keyPressed(FlexContentAssistant.java:47) at org.eclipse.jface.text.contentassist.ContentAssistant$InternalListener.verifyKey(ContentAssistant.java:811) This causing the CPU to spin up to 50%, and eclipse hangs. Bottom line, I will change my setting to 4 times what it current is, and see if I can reproduce. (Only reason I haven't yet, is that I need to reboot I think the owner will reveal who is causing the lock contention that makes the WorkerPool create so many Workers.

The JVM has an interesting implementation, by which the more memory is allocated for the heap (not necessarily used by the heap), the less memory available in the stack, and since Starting debugger from the debug perspective somtimes freezes with alot of empty entries in the thread list. No obvious errors. You should now start to understand the source of your problem… The high level thread creation process is as per below: A new Java thread is requested from the Java program

We do use memory mapped files, so I'll put my focus on those.

However, it breaks all command-line `lein` tasks, making Leiningen nonexistent for this project until I delete the .classpath file, which breaks the Eclipse project... -- You received this message because you Is eclipe.ini the wrong place to put GC log parameters? We use jstack a lot, and if it works, it works fine.
