apped or Direct buffer memory
This error occurs when the Java Virtual Machine (JVM) runs out of memory allocated for direct buffers or mapped files. Direct buffers are a type of buffer that is allocated outside of the normal Java heap, and is used for I/O operations. Mapped files are a type of file that is mapped into memory.
To solve this issue, you can try the following:
1. Increase the memory allocated to the JVM using the -Xmx option. For example, you can set the maximum heap size to 4 GB by passing the following option to the JVM: -Xmx4g.
2. Reduce the amount of memory used by your application. You can do this by optimizing your code, using more efficient data structures, or reducing the size of your data.
3. Use a different I/O mechanism that does not rely on direct buffers or mapped files.
4. Use a profiling tool to identify memory leaks or other memory usage issues in your application.
5. If none of the above solutions work, consider upgrading your hardware to increase the amount of physical memory available to the JVM.
