Therefore, you have to check if your OS allows you enough processes for user. Especially if it's such a round number as 32k, a limit of one kind or another is a very likely culprit.

The diagnostic can be a bit more complex but the key analysis point will be to determine which processes are causing a full OS virtual memory depletion. share|improve this answer answered Mar 6 '14 at 22:06 user3390284 111 add a comment| up vote 1 down vote You have a chance to face the java.lang.OutOfMemoryError: Unable to create new If you have any questions, please contact customer service. an established baseline.
splitting your application processing across more physical or virtual machines. Awesome! They can control how the processes run and impose limits on threads, memory, and so on. Can anyone help please ?
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 When using a 64-bit VM, the true limit will depend on the OS physical and virtual memory availability and OS tuning parameters such as ulimitc. You can change it in Standalone mode by varying the JAVA_OPTS as in the following example: JAVA_OPTS="-Xms128m -Xmx1303m -Xss256k" In Domain Mode, you can configure the jvm element at various level Java.lang.outofmemoryerror: Unable To Create New Native Thread Windows Out of swap space?

Your system does most likely not have thousands of processor cores, creating so many threads is not useful. This is set to non-zero in order to close the connection after specified number of milliseconds idle time.
Native memory is then allocated (reserved) from the OS to the Java process native memory space; assuming the process has enough address space (e.g. 32-bit process) to honour the requestThe OS Cant we increase the limit of threads in OS when we know that there is 50% memory left on the server. –Deepak Tewani May 28 '13 at 10:35 1 We The first of these is the number of currently executing kernel scheduling entities (processes, threads); this will be less than or equal to the number of CPUs. Also check you ulimits (ulimit -a), remember that pretty much everything in Linux/Unix is a file, so also check how many open files are allowed per user.
