根因分析

消息超过了默认的 4MB gRPC 接收限制。服务器发送的载荷大于客户端的 MaxCallRecvMsgSize（或反之）。

English

A message exceeded the default 4MB gRPC receive limit. The server sends a payload larger than the client's MaxCallRecvMsgSize (or vice versa).

解决方案

  1. 90% 成功率 
    Raise both send and receive limits on client and server:
// client
conn, err := grpc.NewClient(addr,
    grpc.WithDefaultCallOptions(
        grpc.MaxCallRecvMsgSize(16*1024*1024),
        grpc.MaxCallSendMsgSize(16*1024*1024),
    ),
)
// server
srv := grpc.NewServer(grpc.MaxRecvMsgSize(16*1024*1024), grpc.MaxSendMsgSize(16*1024*1024))
  2. 85% 成功率 
    Switch large payloads to gRPC streaming so messages are chunked:
stream, err := client.Upload(ctx)
for _, chunk := range chunks {
    if err := stream.Send(&pb.Chunk{Data: chunk}); err != nil { return err }
}
return stream.CloseAndRecv()

无效尝试

常见但无效的做法:

  1. 95% 失败

    The message size is deterministic; retrying sends the same oversized payload and fails identically every time.

  2. 70% 失败

    The send side also enforces MaxCallSendMsgSize; if the server sends a large response, only the receive limit matters, but large requests fail on the server's recv limit.
