[GitHub] [dubbo] hongyu-zxj opened a new issue, #9935: 2.7.10 大response >maxPayload 的异常情况下，出现内存泄露
hongyu-zxj opened a new issue, #9935:
URL: https://github.com/apache/dubbo/issues/9935
<!-- If you need to report a security issue please visit https://github.com/apache/dubbo/security/policy -->
- [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate.
### Environment
* Dubbo version: 2.7.10
* Operating System version: xxx
* Java version: 1.8
### Steps to reproduce this issue
1. 生产者处理大的response
2. 大于maxPayload ,抛出异常
3. 内存飙高好几倍，jmap后，内存等不到回收，一直持续，只能重启
Pls. provide [GitHub address] to reproduce this issue.
### Expected Behavior
<!-- What do you expect from the above steps？-->
### Actual Behavior
<!-- What actually happens? -->
If there is an exception, please attach the exception trace:

可以复现一下，复现方法准备：本地通过visualvm 工具来监听 内存情况，先准备两个dubbo接口，一个是正常调用，一个是response大于maxPayload （建议大于100M左右，太小的我也没有复现）的异常接口；复现步骤：1、调用正常的dubbo接口，查看visualvm 的 byte[]内存情况和MySQLValueObject对象内存占比情况，接口正常返回后再点击visualvm的 perForm GC 触发full GC,再查看 byte[]内存情况和MySQLValueObject对象内存情况；会看到byte[]的内存占比基本恢复到调用前端的情况，MySQLValueObject 对象也消失回收了；2、调用准备好的异常接口，查看visualvm 的 byte[]内存情况和MySQLValueObject对象内存占比情况，可以看到这两项的内存都升高了，而且等接口正常返回了后，这两项的内存占比没有降下去，点击visualvm的 perForm GC 触发full GC后，这两项的内存占比依旧在，并没有回收。

有空通过我上面上的方法进行复现吗？
