根因分析

协程因在通道或锁上永久阻塞而泄漏，导致栈内存无限制增长。

English

Goroutines are leaked because they are blocked forever on channels or locks, causing stack memory to grow unboundedly.

解决方案

  1. 95% 成功率 Use context with timeout to unblock goroutines 
    ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
defer cancel()
select {
case <-ch:
case <-ctx.Done():
    // timeout, handle cleanup
}
  2. 98% 成功率 Ensure every goroutine has a clear exit path 
    done := make(chan struct{})
go func() {
    defer close(done)
    // work
}()
<-done

无效尝试

常见但无效的做法:

  1. Increasing stack limit 95% 失败

    Does not fix the leak; only delays the crash.

  2. Using time.Sleep to periodically check 90% 失败

    Sleep does not unblock goroutines; they remain blocked.
