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. What this means is that the programs written in Java can do several things (seemingly) at once. For example - even on machines with just one processor - while you drag content from one window to another, the movie played in the background does not stop just because you carry out several operations at once. A way java.lang.outofmemoryerror: unable to create new native thread centos to think about threads is to think of them as workers to whom you can submit tasks to carry out. If you had only one worker, he or she could only carry out one task at the time. But when you have a dozen workers at your disposal they can simultaneously fulfill several of your commands. Now, as with workers in physical world, threads within the JVM need some elbow room to carry out the work they are summoned to deal with. When there are more threads than there is room in memory we have built a foundation for a problem: The message java.lang.OutOfMemoryError: Unable to create new native thread means that the Java application has hit the limit of how many Threads it can launch. What is causing it?You have a chance to face the java.lang.OutOfMemoryError: Unable to create new native thread whenever the JVM asks for a new thread from the OS. Whenever the underlying OS cannot allocate a new native thread, this OutOfMemoryError will be thrown. The exact limit for native threads is very platform-dependent thus we recommend to find out those limits by running a test similar to the below example. But, in general, the situation causing java.lang.OutOfMemoryError: Unable to create new native thread goes through the following phases: A new Java thread is requested by an application running inside the JVM JVM native code proxies the request to create a new native thread to the OS The OS tries to cr

VM error and provide you with recommendations and resolution strategies. If you are not familiar with the HotSpot JVM, I first recommend that you look at a high level view of its internal HotSpot JVM memory spaces. This knowledge https://plumbr.eu/outofmemoryerror/unable-to-create-new-native-thread is important in order for you to understand OutOfMemoryError problems related to the native (C-Heap) memory space. OutOfMemoryError: unable to create new native thread - what is it? Let's start with a basic explanation. This HotSpot JVM error is thrown when the internal JVM native code is unable to create a new Java 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...). We http://javaeesupportpatterns.blogspot.com/2012/09/outofmemoryerror-unable-to-create-new.html can clearly see this logic from the OpenJDK1.6 and 1.7 implementations as per below: Unfortunately at this point you won't get more detail than this error, with no indication of why the JVM is unable to create a new thread from the OS… HotSpot JVM: 32-bit or 64-bit? Before you go any further in the analysis, one fundamental fact that you must determine from your Java or Java EE environment is which version of HotSpot VM you are using e.g. 32-bit or 64-bit. Why is it so important? What you will learn shortly is that this JVM problem is very often related to native memory depletion; either at the JVM process or OS level. For now please keep in mind that: A 32-bit JVM process is in theory allowed to grow up to 4 GB (even much lower on some older 32-bit Windows versions). For a 32-bit JVM process, the C-Heap is in a race with the Java Heap and PermGen space e.g. C-Heap capacity = 2-4 GB - Java Heap size(-Xms, -Xmx) - PermGen size (-XX:MaxPermSize) A 64-bit JVM process is in theory allowed to use most of the OS virtual memory available or up to 16 EB (16 million TB) As you can see, if you allocate a large Java Heap (2 GB+) for a 32-bit JVM process, the native memory space capacity will be reduced automatically, opening the door for JV

No wonder – my client has created 6,8K live ReplyReceiverTimer (org.jacorb.orb.ReplyReceiver.Timer). And it seems that already killed threads are not really freed.So starting a jive for instance gives this: khokhria@hzgcttest:~$ jive & [1] 18627 khokhria@hzgcttest:~$ Exception in thread "main" java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start0(Native Method) at java.lang.Thread.start(Thread.java:714) at org.jacorb.orb.ReplyReceiver.
