Webapp not responding until I reload after a day of inactivity

Hi Everyone,

I have a simple web app that becomes unresponsive to a curl POST after being dormant over night. If I use the RELOAD button the curl POST works again. I know there has been a previous post about this a couple of years back that said this should not be the case and no keep 'alive type' scripts or other work-arounds should be needed. However, I have tested extensively over a week now and it is definitely the case.

Please can anyone give any suggestions.

Thanks

Lew

Do you see any errors in the logs corresponding to that behavior?

Hi,

Thanks for the reply. No unfortunately there is nothing in the error log.

Any ideas?

Thanks.

Best

Is it completely empty? Sometimes it takes a while for the file to load

Hi,

The "error" log strangely only shows successful calls, nothing when it hangs. Here is the recent "error" log:

That looks like some sort of logging that your app is printing. Have you tried making a simple GET to your web app just before hitting it with the POST after long inactivity?

Hi,

Thanks for responding, sending a GET first makes no difference. I also have 'stay alive' tasks that run every hour. The internal call to a script to keep hugging face alive is always successful, the external call to the web app starts to fail, can take a day, but once it starts to fail it does not correct. So the server is running fine, its just the web app. A manual reload is needed and then the web app works again. There is nothing in the error log. I will attach a sample from the web app access log below to show the responses, you will see starts with some example successful 200 responses, then becomes 499 and some 504 responses with long response-times. This definitely looks like it is something to do with the internal pythonanywhere.com setup regarding the web app rather than anything I have setup or scripted. Please can you help. I really like the pyhtonanywhere system, I have paid for premium and as I am now moving more into machine learning and python I am hoping to use your servers as my development and production platforms for clients, but I must resolve this issue first.

Thanks again,

Lew

If you are running those "stay alive" calls in the web app, then that is probably the cause of the issue - there is no way to run something hourly inside a web app unless it is part of a request.

Staff glenn | 10061 posts | PythonAnywhere staff | June 7, 2024, 4:03 p.m. | permalink

Hi,

Thanks for your response. The "stay alive" calls are not within the web-app, rather I am using the task system to call a separate function in a python file in my home directory (see function code below). Therefore, I do not think this is the issue. Indeed, the problem was occurring before and the script was a way to try a solve.

Please do you have any other ideas?

Thanks

Lew

Python function run by task scheduler cron job:

def keep_flask_app_alive():

url = "https://LewP.pythonanywhere.com/"

try:

    response = requests.get(url)

    print(f"Keep-alive response for Flask app: {response.status_code}")

    print(f"Response content: {response.text}")  # Print the response content

except Exception as e:

    print(f"Error during keep-alive request for Flask app: {e}")

We've been having problems with the storage server where your account's files are located. We have a partial mitigation in place, but there will still be times when your file access will be too slow. Would you like us to migrate your account to a different file server? There will be a short downtime involved. The process we have in place to do that works well, except that any forum posts you have made in the past will have a username like "deleted-user-1234" associated with them, and if you have a paid account, or have had one in the past, you would not be able to download your past invoices from the "Account" page (though we would be able to provide them on request).

Hi,

Thanks for the response. Yes, that would be great, please migrate my account to a different server.

Thanks again.

Could you contact us on support@pythonanywhere.com to arrange a time to do your migration?

Staff fjl | 5060 posts | PythonAnywhere staff | June 10, 2024, 7:18 a.m. | permalink

Hi,

Thanks for your response. I have sent an email to support@pythonanywhere.com saying there is no need to delay and to do the migration as soon as you can.

Thanks again,

Lew

We will handle it there.

Hi,

Thanks for the migration, after a reload the web app is running again. Hopefully, this will sort my issue.

For others facing similar problems, I have also upgraded to the latest version of the Gradio Client (1.01 at time of writing), as they said the old version could cause intermittent response problems.

I will test over the next week and report back for future users. If all is well, then into production.

Thanks again all responding 'Python Anywhere' staff for your help.

Very best

Lew
