在docker容器内运行时偶尔出现gRPC未知错误

我正在尝试连接运行在docker中的gRPC服务器。但是，我有时会出现以下错误：

File "xxx/grpc/_channel.py", line 826, in __call__
    return _end_unary_response_blocking(state, call, False, None)
  File "xxx/grpc/_channel.py", line 729, in _end_unary_response_blocking
    raise _InactiveRpcError(state)
grpc._channel._InactiveRpcError: <_InactiveRpcError of RPC that terminated with:
    status = StatusCode.UNKNOWN
        details = "Error in service handler!"
