Hello,
This could be a memory leak since you got an Out Of Memory error or possibly related to an update on App Engine. There are many possibilities that could lead to memory leak. All the causes mainly are related to the application itself. These include and not limited to resource memory allocation, as they might not be allocated properly in the application. In addition, I noticed some spikes on the graph provided that could possibly be related to the workload. As the workload increases, it creates more instances and hence causing memory leak. I would suggest to post the issue on Stackoverflow <https://stackoverflow.com/>and the community can definitely be a great help and propose effective solutions.There are some examples that you can refer to as they are similar cases to yours: 1: https://stackoverflow.com/questions/46359298/how-to-fix-memory-leak-in-my-application 2: https://stackoverflow.com/questions/40119/how-to-find-a-java-memory-leak?rq=1 You can also use the Google Stackdriver Debugger <https://cloud.google.com/debugger/docs/using/snapshots>which could be very useful in this case. After checking the solutions, if you believe the issue is related to App Engine, you could post the issue on Google Issue Tracker <https://issuetracker.google.com>, which would allow us to investigate the issue further and if necessary, route it to a specialized team. Carl, I have double checked here on my end and could not find any troublesome updates released on the specified dates. To get information about current and past outages you can use the Google Cloud Status Dashboard <https://status.cloud.google.com/summary>page. Regarding your issue, it has been routed to the specialized team and you will be notified once there is an update. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
