    Application keeps restarting every time umbraco.config file changes v7.15.5

    I am trying to debug an issue where when I try to save and publish, I get
    SQL timeout error. I'm noticing that every time I save and publish, Umbraco restarts. I have never seen logs mentioning Overwhelming Change Notification and sutting down everytime xml file is saved. Any ideas?

    Hi Riadul

    When a file changes inside your Web Application, a File Notification Change message is raised. For example, changing a setting in .config file, you want the application to notice your change and recompile...

    ... but if this setting was changing every few seconds, this would trigger tons of notification requests, and when that happens the application will restart, in the hope of correcting the cause of the notifications.

    It will be interesting to see, and to perhaps bring some immediate relief if you were to set fcnmode="disabled" on your httpruntime element inside the web.config.

    This basically turns off the notifications, and should stop them overwhelming the application.

    However this also means any changes to views etc in the backoffice won't be realised each time they are changed until the application is restarted.,,

    The real interest is, what is writing to the AppLocalResources, AppGlobalResources, AppBrowsers and AppWebReferences folders when a publish event occurs? do you have any .resx resource files in the application?

    Have seen this with Modelsbuilder triggering the shutdown due to files generated at startup, and ImageProcessor too, but not the folders you mention in your post, which makes me think there may be something in your implementation related to these folders, and it's working out what is causing it to 'change'?

    Shannon wrote an article about fcn mode here: https://shazwazza.com/post/all-about-aspnet-file-change-notification-fcn/ but most of the issues this talks about were resolve in 7.6+...

    regards

    Marc
