Again my Azure Web App was down for quite a few minutes (at least 5-10 minutes) in the middle of the day. This was during a low load, but this is a horrible experience for customers.

Requests take forever with giving returning a 503 after a long period of time. When I look in the logs I see low activity and low memory and CPU useage.

I've downloaded the logs and I see the following entries:

Role environment . INITIALIZING
Role environment . INITIALED RETURNED. HResult=-2147024891
Role environment . FAILED TO INITIALIZE. hr: -2147024891
Role environment . INITIALIZING
Role environment . INITIALED RETURNED. HResult=-2147024891
Role environment . FAILED TO INITIALIZE. hr: -2147024891

Does anyone know what's going on? I have two standard instances running.

  • Did you find out the cause? Im having the same issue. Ive recently upgraded our projects to .NET 4.6.1. – gorillapower Sep 28 '16 at 12:19

    @gorrillapower There were two things. One was that the shared storage had problems (see http://stackoverflow.com/questions/35253899/how-does-the-azure-web-apps-architecture-look-like for more information about that). The other problems that I've had for unresponsiveness was lack of memory. Apparently you really quickly run out of memory with the smaller instances - I assume it's because a lot of 'overhead' per instance - for i.e. IIS or something. – Dirk Boer Sep 30 '16 at 19:19
