Hi,
I have a linux azure app service that seems to be restarting itself every 1-2 weeks and I am wondering if there is anything I can do to prevent that from happening.
- My site has Always On enabled.
- There are no errors in the Applicatiom Logs whenever a restart occurs.
- I have Health Check disabled and Scale Out disabled as well as the app is running a stateful background service which there should be only one instance of. These restarts are causing my background service to lose its current progress as well, which is why I'd like them to stop happening.
- The restarts do appear in the Web App restarted (see attached image), but I am unable to tell why they are happening.
Is there a way I can tell what is causing the restarts? Thanks for any help!

Suggestions-
Please go to Diagnose and Solve Problems and look for a restart detector.
This tool can help you find out the possible causes of restarts.
For details refer to- Azure App Service diagnostics overview
Also, can you verify if you have enabled Auto-Heal rules? These rules will trigger a full restart, which will affect processes such as Application Initialization.
See- https://azure.github.io/AppService/2021/04/21/Announcing-Autoheal-for-Azure-App-Service-Linux.html
