The web application nacos appears to have started a thread named nacospublisher-comalibabanacoscommoneventServerConfigChangeEvent but has failed to stop it This is very likely to create a memory leak

Unfortunately, without the complete stack trace of the thread, it is difficult to provide an accurate solution. However, I can provide you with some general suggestions to investigate and resolve the memory leak issue caused by the thread.

1. Analyze the stack trace: The stack trace usually contains information about the methods and classes involved in the thread. Look for any specific code that is causing the thread to hang or not stop properly.

2. Check for thread-related issues: Ensure that the thread is being properly managed and stopped when no longer needed. Look for any missing join() or interrupt() calls that could prevent the thread from stopping.

3. Review the application code: Examine the code related to the web application and the Nacos library. Look for any potential resource leaks, such as unclosed connections or streams, that could cause memory leaks.

4. Monitor memory usage: Use tools like profilers or monitoring tools to analyze the memory usage of the application. Identify any abnormal memory growth or leaks that coincide with the thread's activity.

5. Update Nacos library version: Check if there are any known issues or bug fixes related to memory leaks in the Nacos library. Consider updating to a newer version that may have resolved the problem.

6. Seek help from the Nacos community: If the issue persists, reach out to the Nacos community or support channels for assistance. They may have encountered similar issues or be able to provide specific guidance based on the provided stack trace.

Remember, these suggestions are general and may not directly address the specific issue. Providing the complete stack trace or seeking help from the Nacos community would be the best way to resolve the problem effectively
