What this means is that the programs written in Java can do several things (seemingly) at once. For example - even java.lang.outofmemoryerror: unable to create new native thread centos 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 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

Although there might be plenty of memory available on your machine, you have hit the maximum amount of memory allowed by your JVM, which can be set through the -Xmx parameter The java.lang.OutOfMemoryError: Unable to create new native thread happens whenever the JVM asks for a new thread from the OS. If the underlying OS cannot allocate a new native thread, this OutOfMemoryError will be thrown. 1) Check Threads system wide settings The /proc/sys/kernel/threads-max file provides a system-wide limit for the number of threads. The root user can change that value if they wish to: $ echo 100000 > /proc/sys/kernel/threads-max You can check the current number of running threads through the /proc/loadavg filesystem: $ cat /proc/loadavg 0.41 0.45 0.57 3/749 28174 Watch the fourth field!

Problem https://confluence.atlassian.com/confkb/confluence-crashes-and-throws-outofmemory-unable-to-create-new-native-thread-error-423628320.html The confluence application occasionally crashes and throws anOutOfMemoryErroras below in thecatalina.out,stdoutoratlassian-confluence.log: Exception in thread "http-bio-8506-exec-106" java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start0(Native Method) at java.lang.Thread.start(Thread.java:691) https://bbs.archlinux.org/viewtopic.php?id=207255 at java.util.concurrent.ThreadPoolExecutor.addWorker(ThreadPoolExecutor.java:943) at java.util.concurrent.ThreadPoolExecutor.processWorkerExit(ThreadPoolExecutor.java:992) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:722) Diagnosis Environment In certain cases on Solaris, it appears that this can also cause the Java unable to application to completely crash and generate a core dump. Cause To provide concurrency (the ability to do multiple things at once), Java will spawn operating system threads and use them to perform tasks. Hard limits can be set at the system level on the number of threads that can be created, so if the unable to create application is requesting more threads that the OS is willing to provide, the above error is thrown. This occurs in the following way: A new Java thread is requested by confluence applications. This can be by anything. JVM native code proxies the request to create a new native thread to the OS. The operating system attempts to create a new native thread. As it's a thread, it requires memory to be allocated to it. The operating system refuses the native memory allocation. Thejava.lang.OutOfMemoryError: unable to create new native threaderror is thrown. This can also happen if the operating system has no native memory left to allocate threads (say the 32-bit Java process space has been reached, or the OS virtual memory is fully depleted), or the maximum number of open files has been reached. Workaround Edit the$CONFLUENCE_INSTALL/bin/setenv.shfile and add the below to the top of the file: ulimit -u 4096 ulimit -n 4096 These values may be

Which JVM are you using? I'm using jdk 8u66-1 from the AUR (I have to use Oracle java for my work). I recently switched to Arch on my development machine and have not been able to run my java application (works in ubuntu 14.04 with the same JVM).Like you I played with the ulimits stuff and after a lot of trial and error, my limits are huge:core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 63706 max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 500000 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 99 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 500000 virtual memory (kbytes, -v) unlimited file locks (-x) unlimitedBut like you my java application always crashes with:java.lang.OutOfMemoryError: unable to create new native threadOn my arch machine, while most of the limits set in /etc/security/limits.conf are respected, "nofile" is not, and must be set in /etc/systemd/system.conf "DefaultLimitNOF
