根因分析

服务器写入数据到流的时间过长，超过了配置的写入超时，通常由于网络缓慢或 I/O 阻塞。

English

The server took too long to write data to the stream, exceeding the configured write deadline, often due to slow network or blocked I/O.

解决方案

  1. 通过通道参数配置写入超时：`export GRPC_ARG_HTTP2_WRITE_BUFFER_SIZE=65536` 并设置 `GRPC_ARG_KEEPALIVE_TIME_MS=10000` 以更快检测死连接
  2. 在服务器代码中，使用独立的 goroutine 配合 `context.WithTimeout` 处理写入操作，优雅处理慢客户端

无效尝试

常见但无效的做法:

  1. Increase the overall RPC deadline only, ignoring write deadline 70% 失败

    Write deadline is separate; increased RPC deadline won't fix write-specific timeout.

  2. Restart the server to clear the stream state 80% 失败

    The underlying network issue or blocking I/O persists.

  3. Set a very large write deadline (e.g., 60s) without investigating root cause 50% 失败

    Masks the issue; slow writes can still cause user-perceived timeouts.
