How do I fix a heap dump problem?
Solution 2. Improve or fix the application to reduce memory usage
- Generate a heap dump on OutOfMemoryError. Start the application with the VM argument -XX:+HeapDumpOnOutOfMemoryError.
- Reproduce the problem.
- Investigate the issue using the heap dump file.
How do u identify memory leaks and how do u solve it?
Enable Profiling. Java profilers are tools that monitor and diagnose the memory leaks through the application. They analyze what’s going on internally in our application — for example, how memory is allocated. Using profilers, we can compare different approaches and find areas where we can optimally use our resources.

What causes Java memory leaks?
In general, a Java memory leak happens when an application unintentionally (due to logical errors in code) holds on to object references that are no longer required. These unintentional object references prevent the built-in Java garbage collection mechanism from freeing up the memory consumed by these objects.
How do I debug OutOfMemoryError?
8 Answers
- Enable heap dumps at run time. Run your process with -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/tmp.
- Reproduce the error.
- Fetch the dump.
- Open the dump file with IBM’s Heap Analyzer or Eclipse’s Memory Analyzer.
- Identify areas of largest heap use.
- Fix your code.
Why does heap memory keep growing?
It would be the book keeping data generated by the normal functioning of the VM including that for the GC. The eden goes up and once the GC occurs, the memory used by the heap (eden) is reduced and the cycle starts again.
What could be the possible cause of memory leaks?
Memory leaks are a common error in programming, especially when using languages that have no built in automatic garbage collection, such as C and C++. Typically, a memory leak occurs because dynamically allocated memory has become unreachable.
Which tool is used to detect memory leak in testing?
Using Memory Profilers Memory profilers are tools that can monitor memory usage and help detect memory leaks in an application. Profilers can also help with analyzing how resources are allocated within an application, for example how much memory and CPU time is being used by each method.
