根因分析

在 grpc.Server 的 GracefulStop()/Stop() 完成后，或在 Serve() 启动前发起了调用。

English

A call was made against a grpc.Server after GracefulStop()/Stop() completed, or before Serve() started.

generic

解决方案

  1. 92% 成功率 
    Order shutdown correctly:
// on SIGTERM
srv.GracefulStop() // stops accepting, drains in-flight
lis.Close()
// construct a fresh server on restart
  2. 88% 成功率 
    Guard server lifecycle with sync.Once and a ready channel; only issue calls after Serve() has started (use a health check).

无效尝试

常见但无效的做法:

  1. 95% 失败

    grpc.Server cannot be restarted after Stop; you must construct a new one.

  2. 80% 失败

    Hides a lifecycle bug where the server is being used after shutdown.
