GCC App Engine standard enviroment in Django memory usage fails

From 1 month ago I am experiencing a memory problem in my django app. It is in GCC in GAE + SQL Postgress DB. Apparently I did not modify anything relevant from a memory consumption point of view, getting the error randomly all along the requests.

The error I got is this:

While handling this request, the process that handled this request was found to be using too much memory and was terminated. This is likely to cause a new process to be used for the next request to your application. If you see this message frequently, you may have a memory leak in your application or may be using an instance with insufficient memory. Consider setting a larger instance class in app.yaml.

I am wondering how can I identify the source of this error. Increasing instante minimum type of course decreased the number of errors but they are still present. I do not think my app needs a lot of memory anyway.

Can anybody help me? What can I do?

Thanks,

Pablo

As per the error message,

>While handling this request, the process that handled this request was found to be using too much memory and was terminated. This is likely to cause a new process to be used for the next request to your application. If you see this message frequently, you may have a memory leak in your application or may be using an instance with insufficient memory. Consider setting a larger instance class in app.yaml.

It seems like the requests are utilizing too much memory which causes the insufficient memory.

To mitigate this issue, I would suggest to cross check the below options:

1. Use a larger instance class or upgrade an instance class with more memory based on your application workload, which may help you to resolve this issue.
2. Also make sure the app is catching the SIGTERM signal. If not, the instance is immediately shut down. This was stated in the public Documentation.
3. To reduce the chunks of data you process in each request. You could split it to smaller pieces and keep the smaller instance doing the work.
4. Also have a look at this Stackoverflow Link, as you are trying to configure resource settings in App Engine Standard. The resources section is only configurable in App Engine Flexible. It is suggested adding env: flex in the app.yaml for it to take into effect.

There might be the possibility the error occurs due to a change in the code and try to debug the issue by following the steps provided by @NocommandLine in the Comment section. If the above steps don't help, you may consider contacting Google support as it may require project inspection.
