Hello
Since we don't have visibility on your project to check your App Engine settings including your yaml file and further use our internal tools to find out what is happening, kindly take a look at your configuration such as your max instances, idle time out, and scaling. From your log, the ‘Quitting on terminated signal’ indicates there is a shutdown of an instance [1], it could be that there are no requests hence the instance was shutdown and there could be a spike in subsequent requests that the instance was not ready to respond since there are no instances available. Lastly, kindly take a look at your scaling, do note that there is no guaranteed uptime for basic and manual scaling [3]. Due to this behavior, if you want a higher Monthly Uptime Percentage, try to configure your instance with automatic scaling. You can set the max_instances and max_idle_instances to values that better achieve your architecture in the app.yaml file [4] [1] https://cloud.google.com/appengine/docs/standard/go/how-instances-are-managed#shutdown [2] https://cloud.google.com/appengine/docs/standard/python3/configuring-warmup-requests [3] https://cloud.google.com/appengine/docs/standard/go/how-instances-are-managed#instance_uptime [4] https://cloud.google.com/appengine/docs/standard/go/config/appref#scaling_elements On Thursday, April 21, 2022 at 10:30:00 AM UTC-4 [email protected] wrote: > I think no issue on application side.
