GC overhead limit exceeded
GC overhead limit exceeded is an error message that occurs when the Java Virtual Machine (JVM) is unable to allocate enough memory for garbage collection (GC) to clean up the heap. This error occurs when the JVM spends too much time performing garbage collection and not enough time executing application code.
The GC overhead limit is a threshold set by the JVM to prevent it from spending too much time on garbage collection. When the limit is reached, the JVM throws the "GC overhead limit exceeded" error and terminates the application.
To resolve this error, you can try the following:
1. Increase the heap size of the JVM using the -Xmx flag.
2. Increase the GC overhead limit using the -XX:GCTimeLimit and -XX:GCHeapFreeLimit flags.
3. Optimize your application code to reduce memory usage.
4. Identify and eliminate memory leaks in your code.
5. Use a profiler tool to analyze the memory usage of your application and identify areas that need optimization.
6. Consider upgrading to a newer version of Java that has improved garbage collection performance.
WARNING: NMS time limit 0.030s exceeded
This means that the code or program being executed took longer than the allowed time limit of 0.030s to complete. This can be caused by inefficient or poorly optimized code, or by trying to process a large amount of data in a short amount of time. To fix this issue, the code or program may need to be optimized or restructured to improve its efficiency and reduce the processing time. Alternatively, a more powerful hardware or infrastructure can be used to handle the workload.
