    Umbraco 8.6 on azure boot failed exception

    Hi all

    I currently have a handfull of umbraco 8.6.1 websites running on azure, where i have set the recommended settings in appSettings, according to the documentation regarding azure. see the docs. https://our.umbraco.com/documentation/Getting-Started/Setup/Server-Setup/azure-web-apps

    the issue is that sometimes the websites throws the boot failed exception. like yesterday for example all of our umbraco sites were throwing that exception and all of our other sites were running fine. does anyone know of furher configurations or is there any bug fixes on later umbraco versions that have adresses this issue ?

    Best regards Christoffer

    Hi Christoffer,

    There are lots of different reasons for a Boot Failed exception, can you share more details about what the actual error was? You should see more details in the individual error logs for each site.

    Thanks

    Nik

    Hi Nik i checked the logs and i see errors that relates to Examine and lucene. manily 2 errors,

    System.ObjectDisposedException: The CancellationTokenSource has been disposed.
       at System.Threading.CancellationTokenSource.ThrowObjectDisposedException() 
    

    and

    Lucene.Net.Store.AlreadyClosedException: this IndexReader is closed
       at Lucene.Net.Index.IndexReader.EnsureOpen() in d:\Lucene.Net\FullRepo\trunk\src\core\Index\IndexReader.cs:line 204

    Hi Christoffer,

    If you look in your logs, do you see anything about Examine shutting down? Or MainDomLock released? (These will be info entrys not errors)

    The second error you shared makes me think you are suffering from an issue I've been having where the site "half shuts down" causing Examine Manager begin shutting down. Unfortunately there isn't a way for Examine Manager to restart without restarting the entire site.

    Thanks

    Nik

    after alot of digging and checking on our azure database setup. i found that all websites with umbraco version 8.6 that frequently had similar errors/website breaks was running on SQL Databases on Elastic pool and the websites with umbraco versions lower than 8.6 was not breaking on elastic pool databases. so the problems was fixed by upgrading the database to MSSQL T1 database, after that the website stopped breaking frequently. Maybe this could be of some help to others with the same problem
