The "OutOfMemory" error occurs when the Java Virtual Machine (JVM) runs out of memory and cannot allocate more memory to the application. The "GC overhead limit exceeded" error occurs when the garbage collector (GC) spends too much time trying to reclaim memory and fails to free up enough memory. This error is usually caused by the application generating too much garbage, which results in the GC running frequently and taking up too much CPU time.
To resolve this error, you can increase the memory available to the JVM by setting the -Xmx option to a larger value. You can also optimize your application to generate less garbage and reduce the frequency of garbage collection. This can be done by using efficient algorithms, avoiding unnecessary object creation, and using cache mechanisms to reuse objects. Additionally, you can tune the GC settings to make it more efficient by adjusting the GC threshold and other parameters.
