    "Umbraco application starting" out of nowhere

    Hey all,

    I have an interesting situation on my hands.

    From time to time (2-4 times a day) I get "Umbraco application starting" with downtime registered in monitoring tools, but there's nothing in the Event Viewer or Umbraco Logs that indicates what triggers this. (No app pool recycle events, no config change events. The site seems to be functioning normally and then it just restarts out of nowhere.)

    We have App Pool recycling turned off because initialization takes a while, running Umbraco 7.2.6 with uCommerce

    Hi Vaidas

    This is due to asp temporary files and I am assuming you are using Visual Studio?

    On first compile the temp files are created, in essence copies of all "important" data.

    I managed to "stop" the recycling one machine by turning off the anti-virus which was scanning the files and indexing, hence app starts.

    On my current machine Windows 10 VS2015 I have not managed to achieve it, so on writing anything in app_ folders, or web config, IIS Express (or IIS) shuts down and restarts.

    Keep having a look at it to try to overcome it, but haven't achieved it yet.

    If you find anything keep posting and see if we can't help to find a solution.

    Regards

    Gary
