# 服务启动后，状态断断续续处于"告警中"
#### 问题现象
预测流量不大但频繁出现以下报错
- Backend service internal error. Backend service read timed out
- Send the request from gateway to the service failed due to connection refused, please confirm your service is connectable

- Send the request from gateway to the service failed due to connection timeout, please confirm your service is able to process the new request
 
#### 原因分析
该报错是因为发送预测请求后，服务出现停止后又启动的情况。
#### 处理方法
需要您检查服务使用的镜像，确定服务停止的原因，修复问题。重新创建模型部署服务。
