### Pre-check - [x] I am sure that all the content I provide is in English. ### Search before asking - [x] I had searched in the [issues](https://github.com/apache/dubbo/issues?q=is%3Aissue) and found no similar issues. ### Apache Dubbo Component Java SDK (apache/dubbo) ### Dubbo Version Dubbo Version: [3.2.18 Operating System: [e.g., Linux] Java Version: [e.g., JDK 1.8.0_202] ### Steps to reproduce this issue We are experiencing memory leaks in the Dubbo QoS module, specifically in the HttpCommandDecoder class. The leak is caused by ByteBuf objects not being properly released when processing HTTP requests through the QoS interface. the Error Logs: [2025-11-02 08:56:45.424][ERROR][io.netty.util.ResourceLeakDetector][LEAK: ByteBuf.release() was not called before it's garbage-collected. Recent access records: Created at: io.netty.buffer.PooledByteBufAllocator.newDirectBuffer(PooledByteBufAllocator.java:403) io.netty.buffer.AbstractByteBufAllocator.directBuffer(AbstractByteBufAllocator.java:188) io.netty.buffer.AbstractByteBufAllocator.directBuffer(AbstractByteBufAllocator.java:179) io.netty.buffer.AbstractByteBufAllocator.buffer(AbstractByteBufAllocator.java:116) io.netty.handler.codec.http.multipart.HttpPostStandardRequestDecoder.offer(HttpPostStandardRequestDecoder.java:295) io.netty.handler.codec.http.multipart.HttpPostStandardRequestDecoder.<init>(HttpPostStandardRequestDecoder.java:158) io.netty.handler.codec.http.multipart.HttpPostRequestDecoder.<init>(HttpPostRequestDecoder.java:95) io.netty.handler.codec.http.multipart.HttpPostRequestDecoder.<init>(HttpPostRequestDecoder.java:53) org.apache.dubbo.qos.command.decoder.HttpCommandDecoder.decode(HttpCommandDecoder.java:58) org.apache.dubbo.qos.server.handler.HttpProcessHandler.channelRead0(HttpProcessHandler.java:89) <img width="1255" height="755" alt="Image" src="https://github.com/user-attachments/assets/e1c6b07d-5701-465f-95c4-6099abaa6925"; /> <img width="1046" height="740" alt="Image" src="https://github.com/user-attachments/assets/1d932dda-0409-4c70-8c68-60d13fcd84cc"; /> ### What you expected to happen The memory leak occurs in: org.apache.dubbo.qos.command.decoder.HttpCommandDecoder.decode() at line 58 When creating HttpPostRequestDecoder for HTTP command processing The allocated Direct ByteBuf objects are not properly released in certain code paths ### Anything else The memory leak is triggered whenever someone executes any QoS-related command on a production machine. ### Are you willing to submit a pull request to fix on your own? - [x] Yes I am willing to submit a pull request on my own! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
