Hello! Friends, today we will discuss the GC overhead limit exceeded, that is, the so-called “OutofMemory” issue/error in the Java programming language. There are a lot of programmers who love to code in the Java programming language. Many of you may have sometimes encountered this error in your PC while working with the Java programming language.
The GC overhead limit exceeded error is from the family of java. Lang.OutOfMemoryError indicates a resource (memory) exhaustion. As a result, certain categories of application program bugs are eliminated or substantially reduced by GC. This article will look at the “GC overhead limit exceeded” error that you come across sometimes and how to fix this error? So let’s get into it.
What is the GC overhead limit exceeded?
The java. Lang.OutOfMemoryError is thrown due to lack of memory space available. The Java virtual machine shows the error to point out that the application is spending more time in garbage collection (GC) than useful work. Ti free up the memory, the JVM stops the application from running for at least a short time. The collector is responsible for Garbage detecting objects that are not being used or referenced, and collected. In this manner, memory space is being reclaimed for java applications.
This means all the threads, except for the GC threads, will stop executing until the GC threads are executed and the garbage collector frees up the objects. Garbage collection consumes CPU resources to decide which memory to free; however, in some cases, the garbage collector cannot reclaim portions of memory even though these objects are no longer accessible by Java applications. These are called memory leaks and can severely limit the available memory space. JVM throws this error when the application spends 98% of the time in garbage collection.
As per Java, the JVM is designed to throw this error if the Java process spends more than 98% of its time doing GC and less than 2% of the heap is recovered in each run. In simple words, it means that the respected application has exhausted nearly all the available memory space, and the garbage collector has spent much of its time trying to clean it and has failed repeatedly.
In such cases of errors, what happens is, users, can notice that the application is working slower than ever before; that is, it is performing the tasks in long-duration than the operations that used to be completed within milliseconds. This happens because the CPU uses its entire garbage collection capacity and takes more time to complete other tasks.
Solution for this error:
The garbage collection can impact the performance of Java applications in unpredictable ways. It adds many CPU loads and slows down the application’s processing—the cause behind the java. Lang.OutOfMemoryError is a memory leak. Therefore you need to have the solutions for such problems before they can cause PC huge damage. So, to solve it, you can allocate more memory space to it. But it says that allocating more memory to Java will not work, which is postponing java. Lang.OutOfMemoryError.
So to prevent this memory leak, here are some steps that you can follow and get rid of it:
- Find the object in your Java application that is occupying more memory space. Identify that object which is taking almost more space in the application’s memory.
- Know where these objects are being located in your application.
- Identify the place where these objects are allocated the memory space in the application.
- Know what is currently referencing these objects.
- Try not to create temporary or referenced objects in large amounts, as it causes memory leakage.
Solution for java.lang.OutOfMemoryError in Minecraft:
Minecraft is a video game; sometimes, it also gives java. Lang.OutOfMemoryError in your PC. It does not let you play the game; it gets stuck in the middle of the game and more problems you may face. Here is the solution which can help prevent memory leakage in Minecraft:
- First of all, you need to know how much memory space you have on your PC.
- Then follow this path in your PC: search for control panel->System->Advanced System setting->Environment Variables-> then change the java value to 1GB or 2GB or 3GB.
- Now, this comes back to the control panel then go-to Java->Java tab->View->change it into the same number given above->
- Now launch the Minecraft game and click on the edit.
- Click on more options and then change the -XMX number same as above.
- Just save the change and relaunch the game.
Conclusion
Many of you may have sometimes encountered this error in your PC while working with the Java programming language. The java. Lang.OutOfMemoryError is thrown due to lack of memory space available. As explained, this error is a memory leakage problem. What is this error that is causing trouble in your PC, and how to fix this problem? Everything is provided here in this article. In this article, we explained java. Lang.OutOfMemoryError GC overhead limit exceeded error and the reasons behind it. I hope this will help you or your friend or anyone who is a programmer or a gamer.
