根因分析

服务器正在正常关闭，导致所有活跃流被关闭。

English

The server is gracefully shutting down, closing all active streams.

解决方案

  1. Implement client-side reconnection logic with exponential backoff. Example in Python: `channel = grpc.insecure_channel('target', options=[('grpc.service_config', '{"methodConfig": [{"name": [{}], "retryPolicy": {"maxAttempts": 5, "initialBackoff": "0.1s", "maxBackoff": "1s", "backoffMultiplier": 2, "retryableStatusCodes": ["UNAVAILABLE"]}}]}')])`
  2. Use a load balancer to route requests to healthy server instances.

无效尝试

常见但无效的做法:

  1. 80% 失败

    The server is down; retries will fail until the server is back.

  2. 60% 失败

    Keepalive settings do not prevent server shutdown from closing streams.

  3. 95% 失败

    The stream is permanently closed; a new stream must be created.
