What version of Umbraco are you using? And has it been acting like this all the time or did it just start to happen? If so what changes have been made? Any custom stuff that could be the cause of this?
The website is currently a version 7.2.1. It is an old site and has been updated several times. It started out as a 4.something.
As for special IIS settings; the app pool has a CPU limit of 85% in 4 minutes -> killW3wp. This rarely occurs, and not at the same time as the “Application shutdown”s.
I am not sure for how long we have had this problem; no one has paid it any attention as it is marked [info] in the log ;)
We had a very similar issue, although the reasons were limited to "ConfigurationChange".
It happened regularly, even though the configuration files had not been updated (according to the date time stamps).
We added exclusions to the iis web folder for McAffee and the problem stopped.
It may be worth checking / temporarily disabling any virus checking software, to diagnose if this is the cause.
This sounds like the issue over here: http://issues.umbraco.org/issue/U4-6338
If this is indeed your problem then there's a patch available in the comments that will hopefully help.
That's the one I'm referring to: the patch of the patch. Basically, our servers are as up-to-date as they need to be.
I'm starting to believe our issues might be related to load-balancing, so I'm going over that documentation for the 10th time just to make sure our set-up is properly configured before continuing to debug. It doesn't help that these errors are so similar to what others are having trouble with.
Our files were located on a network share. Moving the files to the webservers filesystem helped in our case. Properly the problem/solution in Sebastiaan post.
@sebastiaan,
That is a VERY interesting article and I'm surprised I haven't come across it yet. I've implemented the suggestion in the article by changing the FCN Mode to 'Single'. I will return here if this has helped reduced the application shutdowns.
Application shutdown. Reason: "various"
Hi,
Im geeting "Application shutdown." in my log every half/one hour.
The resons differ:
Application shutdown. Reason: ConfigurationChange
Application shutdown. Reason: BinDirChangeOrDirectoryRename
Application shutdown. Reason: HostingEnvironment
The files have not been touched when the error ocures
The server is a Windows 2008 R2. The website folder i located on a share.
Anyone have any experience with this?

Hi Thomas and welcome to our :)

Any weird IIS settings that could be the cause?

Thanks for the suggestion – I will passed the question about antivirus to the hosting center.
I have also read somewhere that Examine/Lucene index in some case could “stress” IIS to think files are changing when they are not.

Hi Sebastian,
The server we are running on is a Windows 2008 R2 - does the patch apply to that also?
/Thomas
We don't know for sure, please check if the mentioned security patches are indeed installed on your server, if so this fix might help.
The server does not have KB3000850 or KB3007507 installed.
Hello, Thomas.
Did you ever get these issues resolved? I'm having similar problems on a 2012 server (with the MS patch).
Which patch? There's a patch for the broken patch (
KB3052480) in case you didn't notice.That's the one I'm referring to: the patch of the patch. Basically, our servers are as up-to-date as they need to be.

You could also have a look at this one, might help for others with this problem as well: http://www.shazwazza.com/post/all-about-aspnet-file-change-notification-fcn/

This is the first time I've read that article as well. Probably because it was just published today :-)
Doh, my bad XD
Since I've made the change to the FCN Mode, I am getting much less application restarts.
is working on a reply...
