根因分析

创建time.Timer或time.Ticker而不停止它们，导致协程泄漏和内存耗尽。

English

Creating time.Timer or time.Ticker without stopping them, causing goroutine leak and memory exhaustion.

generic

解决方案

  1. 95% 成功率 Always stop timers and tickers when done 
    ticker := time.NewTicker(time.Second)
defer ticker.Stop()
for range ticker.C {
    // do work
}
  2. 85% 成功率 Use time.After with select and timeout 
    select {
case <-ch:
case <-time.After(5 * time.Second):
    // timeout
}

无效尝试

常见但无效的做法:

  1. Using time.After repeatedly without reset 90% 失败

    time.After creates new timer each call; old timers are not garbage collected until fired.

  2. Ignoring ticker stop in defer 80% 失败

    Ticker continues to tick; goroutine leaks.
