通讯超时锁表了

- [ ] I have searched the [issues](https://github.com/codingapi/tx-lcn/issues) of this repository and believe that this is not a duplicate.

### 1. Bug Description
A向库插数据，然后A->B,A->C：
当并发开到1000时候，当A->B，或者A->C出现调用超时的时候，A库锁表了，当A模块重启后恢复正常
并发数200,400，500都正常，设置到1000的时候出问题了

### 2. Environment:
- JDK version: 1.8
- OS: win10
- TX-LCN version: 5.0.2.release
- Others:

### 3. Exception Stacktrace
1. 常见的springboot ribbon调用超时报错，A模块提示连接B,C超时
2. DTXServiceExecutor： business code error @group（d93327fe8536）
注：内网不方便截取报错信息
Flipping property: spring
```
Paste your Exception Stacktrace here!
```

### 4. Tour Idea

The report names A/B/C modules, JDK 1.8, TX-LCN 5.0.2.release, Spring Boot Ribbon timeouts, and DTXServiceExecutor; no source file or test is provided. Start by reproducing the A→B/A→C timeout at concurrency 1000 and capture the missing exception details, then verify whether the lock clears without restarting module A.
