Root Cause

A parent context was canceled (or timed out) while a child operation was in progress. The error surfaces from HTTP clients, DB queries, or custom code checking ctx.Err().

generic

中文

父上下文被取消（或超时），而子操作仍在进行。错误来自 HTTP 客户端、数据库查询或检查 ctx.Err() 的自定义代码。

Workarounds

  1. 92% success 
    if err := ctx.Err(); err != nil {
    return err
}
  2. 85% success 
    retryCtx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
defer cancel()
resp, err := client.Do(req.WithContext(retryCtx))

Dead Ends

Common approaches that don't work:

  1. 95% fail

    The context remains canceled; retries fail instantly without making a request.

  2. 80% fail

    Ignores the caller's shutdown intent; leaks work after the request is abandoned.
