根因分析

客户端为 RPC 设置了截止日期（通过 context.WithTimeout 或 context.WithDeadline），但服务器响应时间超过了允许的时间。

English

The client set a deadline (via context.WithTimeout or context.WithDeadline) for the RPC, but the server took longer to respond than the allowed time.

解决方案

  1. 70% 成功率 
    Profile the handler and reduce database queries or external calls.
  2. 80% 成功率 
    ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second); defer cancel(); for i := 0; i < 3; i++ { err := client.Call(ctx, ...); if err == nil { break }; time.Sleep(time.Duration(i)*time.Second) }

无效尝试

常见但无效的做法:

  1. 40% 失败

    This may hide the underlying performance issue and cause long hangs.

  2. 90% 失败

    The server may have partially processed the request, leading to inconsistency.
