This limit is specified during application startup. To make things more complex, Java memory is separated into two different regions. These regions are called Heap space and Permgen (for Permanent Generation): The size

of those regions is set during the Java Virtual Machine (JVM) launch and can be customized by specifying JVM parameters -Xmx and -XX:MaxPermSize. If you do not explicitly set the sizes, platform-specific defaults will be used. The java.lang.OutOfMemoryError: Java heap space error will be triggered when the application attempts to add more data into the heap space area, but there is not enough room for it. Note that there might be plenty of physical memory available, but the java.lang.OutOfMemoryError: Java heap space error is thrown whenever the JVM reaches the heap size limit. What is causing it?There most common reason for the java.lang.OutOfMemoryError: Java heap space error is simple - you try to fit an XXL application into an S-sized Java heap space. That is - the application just requires more Java heap space than available to it to operate normally. Other causes for this OutOfMemoryError message are more complex and are caused by a programming error: Spikes in usage/data volume. The application was designed to handle a certain amount of users or a certain amount of data. When the number of users or the volume of data suddenly spikes and crosses that expected threshold, the operation which functioned normally before the spike ceases to operate and triggers the java.lang.OutOfMemoryError: Java heap space error. Memory leaks. A particular type of programming error will lead your application to co

It's normal as JMeter by default has a very low heap allocation. It's controllable via -Xmx parameter. There is a line in jmeter.bat or jmeter.sh script which recommends launching JMeter as JVM_ARGS="-Xms512m -Xmx512m" jmeter.sh You can try increasing maximum heap until you'll stop receiving these errors. I'd recommend to set it to something like 80% of your hardware RAM. Also consider JMeter Performance and Tuning Tips article to ma
Contents Previous Next 3.2 Understand the OutOfMemoryError Exception One common indication of a memory leak is the java.lang.OutOfMemoryError exception. Usually, this error is thrown when there is insufficient space to allocate an object https://docs.oracle.com/javase/8/docs/technotes/guides/troubleshoot/memleaks002.html in the Java heap. In this case, The garbage collector cannot make space available to accommodate a new object, and the heap cannot be expanded further. Also, this error may be thrown when there is insufficient native memory to support the loading of a Java class. In a rare instance, a java.lang.OutOfMemoryError may be thrown when an excessive amount of time is being spent doing error java garbage collection and little memory is being freed. When a java.lang.OutOfMemoryError exception is thrown, a stack trace is also printed. The java.lang.OutOfMemoryError exception can also be thrown by native library code when a native allocation cannot be satisfied (for example, if swap space is low). An early step to diagnose an OutOfMemoryError exception is to determine the cause of the exception. Was it thrown because java heap space the Java heap is full, or because the native heap is full? To help you find the cause, the text of the exception includes a detail message at the end, as shown in the following exceptions. Exception in thread thread_name: java.lang.OutOfMemoryError: Java heap space Cause: The detail message Java heap space indicates object could not be allocated in the Java heap. This error does not necessarily imply a memory leak. The problem can be as simple as a configuration issue, where the specified heap size (or the default size, if it is not specified) is insufficient for the application. In other cases, and in particular for a long-lived application, the message might be an indication that the application is unintentionally holding references to objects, and this prevents the objects from being garbage collected. This is the Java language equivalent of a memory leak. Note: The APIs that are called by an application could also be unintentionally holding object references. One other potential source of this error arises with applications that make excessive use of finalizers. If a class has a finalize method, then objects of that type do not have their space reclaim
