根因分析

在调用 grpc.Server.Stop() 或 GracefulStop() 后，处理器仍尝试在流上发送。常见于关闭期间未排空进行中的处理器。

English

A handler attempted to send on a stream after grpc.Server.Stop() or GracefulStop() was called. Common during shutdown when in-flight handlers are not drained.

generic

解决方案

  1. 95% 成功率 
    Use GracefulStop with a timeout fallback:
done := make(chan struct{})
go func() {
    grpcServer.GracefulStop()
    close(done)
}()
select {
case <-done:
case <-time.After(30 * time.Second):
    grpcServer.Stop()
}
  2. 90% 成功率 
    Check ctx.Err() before each Send in streaming handlers:
if err := stream.Context().Err(); err != nil {
    return status.FromContextError(err).Err()
}

无效尝试

常见但无效的做法:

  1. 80% 失败

    Restarting does not drain in-flight handlers; the error recurs on the next shutdown.

  2. 75% 失败

    Clients receive truncated responses and may retry with stale state.
