![]() Method 4: Use a Low-Memory Footprint Garbage Collector ![]() Step 7: Fix Memory Issuesįix memory issues identified by the heap dump analysis by optimizing memory usage in your Java application, such as by reducing object creation, optimizing data structures, or increasing memory allocation.īy using a memory profiler such as Java VisualVM, you can effectively identify and fix memory-related issues in your Java application, including the : GC overhead limit exceeded error. ![]() Step 6: Analyze Heap DumpĪnalyze the heap dump generated by the jmap command-line tool using a tool such as Eclipse Memory Analyzer or VisualVM Heap Dump Analyzer. This command generates a heap dump in binary format ( -dump:format=b) and saves it to a file named heapdump.bin ( file=heapdump.bin) for the Java application with the specified PID ( ). Here's an example of how to use the jmap command-line tool to generate a heap dump for further analysis: Optimize memory usage in your Java application by using the information provided by Java VisualVM to identify and address memory leaks, inefficient memory usage, and other memory-related issues. Step 4: Analyze Memory UsageĪnalyze memory usage in your Java application by exploring the different tabs and views in Java VisualVM, such as the Heap Dump, Memory, and Threads views. Step 3: Connect to Your Java ApplicationĬonnect Java VisualVM to your Java application by selecting it from the list of running applications or by providing its PID. Launch Java VisualVM from the command line or from your IDE. Here's an example of how to use the Java VisualVM memory profiler to identify and fix the issue: Step 1: Install Java VisualVMĭownload and install Java VisualVM from the official website. When encountering the : GC overhead limit exceeded error, one approach to fixing it is to use a memory profiler to analyze and optimize memory usage in your Java application. out :: println ) īy following these tips, you can reduce the number of objects created in your code and avoid the ": GC overhead limit exceeded" error. Example of using streams and lambdas int numbers = new int for ( int i = 0 i n % 2 = 0 ).
