A Started Service Is Intermittently in the Alarm State

Symptom

The traffic for prediction is not heavy, but the following error frequently occurs:

• 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

Possible Causes

After a prediction request is sent, the service stops and then starts.

Solution

Check the image used by the service, identify the cause of the service stop, and rectify the fault. Re-create the AI application and use it to deploy a service.
