根因分析

time.Tick 返回的通道永远不会被垃圾回收；每次调用都会为进程生命周期泄漏一个 goroutine。

English

time.Tick returns a channel that is never garbage collected; each call leaks a goroutine for the process lifetime.

解决方案

  1. 95% 成功率 
    t := time.NewTicker(time.Second)
defer t.Stop()
for range t.C { /* ... */ }
  2. 90% 成功率 
    timer := time.AfterFunc(time.Second, func() { /* ... */ })
defer timer.Stop()

无效尝试

常见但无效的做法:

  1. 90% 失败

    Each new ticker adds a goroutine; long-running services leak unboundedly.

  2. 95% 失败

    time.Tick's underlying ticker is intentionally retained by the runtime.
