    Umbraco application keeps restarting (hosted on Azure Cloud Service)

    Hi,

    I am running Umbraco on an Azure Cloud Service (A1 instance: 1 core, 1.75Gb RAM, Windows Server 2012) and the application keeps restarting - it seems to do this each time I publish something! I don't see this error on my laptop (8.1 Pro) so I'm assuming it's something to do with the hosting environment?

    I am intercepting the Publish event and inserting data from the Umbraco content item into a second database, but that process all sees to be running fine.

    Here's a 'debug' version of the Umbraco log file where you can see the publish happening at the top, and then 15 seconds later the "Umbraco.Core.CoreBootManager - [Thread 8] Umbraco application starting" message appears:

    As you can see from the log file, there are no errors being logged that seem to be causing this...

    The only Umbraco package I have installed is uSync, but I've tried uninstalling that and it makes no difference...

    Any ideas or solutions much appreciated!

    Thanks,

    Unfortunately this is due to a update from Microsoft that's installed on your server, they're working on it. More info and a workaround here:

    Thanks Sebastiaan - I'm going to deploy to a bigger instance (the A2 with 3.5Gb RAM) to see if this gets around the problem for now...

    It will make 0 difference, it's not a performance problem it's a problem in their code which they have identified. There's nothing you can do if you cannot uninstall the update. I have my fingers crossed for a fix in the next windows update (second Tuesday of the month), though that doesn't help you now unfortunately.

    Ah ok - you're right it didn't make any difference, just slightly improves the application start-up time... :)

    Will keep my fingers crossed for that Windows Update then!

    Thanks for the info :)

    Do you know if this issue was ever resolved?

    I've tried a whole bunch of things, and the site seems to be running ok, then occasionally it will appear to restart, where it reloads in views, etc. to the cache.

    I have more detail here if you get a chance to look at what I've been battling: https://stackoverflow.com/questions/44099297/performance-issue-umbraco-on-azure

    Thanks
