根因分析

所有协程都在等待通道或锁，无法继续执行，通常是由于循环依赖或缺少发送/接收操作。

English

All goroutines are blocked waiting on channels or locks with no possibility of progress, typically due to circular dependencies or missing sends/receives.

generic

解决方案

99% 成功率 Ensure each channel send has a corresponding receive in another goroutine
```
ch := make(chan int)
go func() {
    ch <- 1
}()
result := <-ch
```

85% 成功率 Use buffered channels to avoid blocking

ch := make(chan int, 1)
ch <- 1
// no receiver needed immediately

无效尝试

常见但无效的做法:

Adding more goroutines to break the deadlock 95% 失败
More goroutines will also block if they follow the same pattern, exacerbating the issue.
Using time.Sleep to wait for conditions 90% 失败
Sleep does not resolve the fundamental blocking; it only delays the deadlock detection.
