# 资源耗尽：gRPC 接收的消息大于最大值（8388608 vs. 4194304）

- **ID:** `grpc/client-side-streaming-too-large`
- **领域:** grpc
- **类别:** resource_error
- **验证级别:** ai_generated
- **修复率:** 85%

## 根因

客户端发送的消息超过了服务器配置的最大消息大小。

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |
|------|------|------|------|
| gRPC Python 1.48.0 | active | — | — |
| gRPC C++ 1.50.0 | active | — | — |

## 解决方案

1. ```
   Set the max message size on both client and server. On the server, use `grpc.max_receive_message_length` option. Example: `server = grpc.server(futures.ThreadPoolExecutor(), options=[('grpc.max_receive_message_length', 16 * 1024 * 1024)])`
   ```
2. ```
   Compress the payload using gRPC's built-in compression. Enable with `grpc.Compression.Gzip` on channel or call.
   ```

## 无效尝试

- **** — The server still enforces its own limit, so the error persists. (70% 失败率)
- **** — Negative values are ignored by gRPC; the default limit applies. (40% 失败率)
- **** — The same size violation will occur again without configuration change. (90% 失败率)
