Description:
Application pool 'DefaultAppPool' is being automatically disabled due to a series of failures in the process(es) serving that application pool.
Please provide near solution for this problem. I will appreciate the suggestion
IIS comes with a feature called Rapid-Fail Protection. By default an App Pool is configured to become disabled if a worker in the pool crashes 5 times within a 5 minute span.
The thresholds of this setting are able to be modified by right clicking on the App Pool going to Advanced Settings and modifying the 'Rapid-Fail Protection' properties. However, this event indicates that there is likely a serious issue in your application that needs to be resolved.
I got tensed about this issue and finally i got solved.
Please make sure that the following option is correct in Advance Settings in Application pool.
Application Pools>Default Application Pool > Right click and select Advance Settings.
And then check whether the option "Enable 32 bit applications" has been set as "False". It should be False
I got solved by did the above change.
I Got this error when i installed URL Rewrite Module, install correct URL Rewrite Module to fix this.
To verify this error cause of URL Rewrite Module check events logs .
windows logs>> System>> Click on recent Error, In Error details
it will show "Application pool 'DefaultAppPool(or
YourApplicationpool)' is being automatically disabled due to a
series of failures in the process(es) serving that application
pool."
Windows logs>> Application>> click on recent error, In error
details it will show "The Module DLL
'C:\Windows\system32\inetsrv\rewrite.dll' failed to load. the data
is the error."
I hope this will help You.
It's a registry permission issue. This should help:

You might also need to add read/write permissions for NT AUTHORITY\NETWORK SERVICE (or NT AUTHORITY\SYSTEM or the account used by your application pool) to c:\Windows\TEMP.

I have a website which has been up and running absolutely fine for about 8 months now. It's running .net 4 intergrated mode.
Recently i've started to get some "random" w3wp.exe crashes, and after 5 of them, IIS rapid fail protection kicks in and I have to manually login to the server and start the application pool again.
Here's what the event viewer says for the Error:
Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7afa2

Report Id: d9cf3164-da5e-11e2-8cc5-f46d0440f6d5
Straight after the crashes, i get an "Information" log in the event viewer which at the bottom gives me the location of a .wer file.

That nlssorting.dll seems to crop up a lot but I can't seem to find anything online related. The only thing I can find which matches my error is here, but that doesn't really help me.
I'm completely stumped as to where to go from here to fix this. Here's what I've tried:
Loading up IIS log files and trying every request from about 30 minutes before a crash, and none of the pages cause any errors.
Searching my code for any recursion which might cause a stackoverflow, but there isn't any
trawling online for ANYTHING that might help
Has anyone else ever had any problems with nlssorting.dll ? Can i get some more information from the .wer file that might help me pin point where this is happening?
Thanks in advance for any help!
UPDATE
I was using a 3rd party DLL, which was causing a stack overflow exception (0xc00000fd)
After more investigation, it was only happening after a certain chain of events happened - hence the "random" in the title. Removing the DLL fixed the problem.
We had the same problem with one of our sites. Using SVN we tracked it down to a method that was scaning for images within a folder.
I modified the code as follows:
Checking array length of scan results to be > 0 instead of == 1
Adding CultureInfo.InvariantCulture to all Int32.ToString() calls
After this we no longer experienced the error. The exact reason is still unknown.
I believe that none of the above points should make a difference in our environment. I believe that the problem could have been, people modifying image files and folders while the image scanning method was called.
I hope this helps somebody.
For anyone who's curious, this is a PITA to debug. Here are three reasons rumored for this to happen:
(1) Stack overflows, as in the original post.
(2) Too much CPU / memory usage, which becomes obvious and rapid fail protection closes the process.
(3) Unable to respond to pings / requests due to application hogging resources, but in a way that rapid fail protection deems appropriate to end the process, not explicitly because of either (1) or (2).
Our solution was to add manual log tracing in the production environment until we eventually found recursion which was leading the application to be stopped by reliability services (for inability to respond to pings, or process randomly crashing) rather than throwing an in-application exception.
I had the issue where w3p would throw an unhandled error as soon I spun up the site\api URI from the web browser, then it would crash.
I was able to pinpoint what part of my code was causing it in my case it was in the Owin Startup class and I was reading some configuration records from a database but prior to that it gets the connection string from a configuration file outside of the web app directory.
I checked the ownership of the folder it showed my account but apparently the subfolders were not owned by me so I set ownership to me again, clicked OK to allow permissions to traverse the objects and voila bye bye w3p error and the API loaded.
So in my case it was an access denied error on the folder \ file that contained the connection string.
I'm having trouble hunting down an issue where an ASP.NET 4 application fails while trying to get user groups for a given user from time to time. The application pool associated with this application is setup to run under ApplicationPoolIdentity.
Exception Info
System.DirectoryServices.DirectoryServicesCOMException

Message: An operations error occurred.

95%-99% of the time, this function works fine, but from time to time, it just starts failing. When I change the application pool to use LocalSystem or NetworkService, it starts working. When I change back to ApplicationPoolIdentity it begins failing again. The only way to get the site working again with ApplicationPoolIdentity is to reboot the server.
I was able to find a similar issue here, but the resolution was a reboot as well. I'd like to find a more permanent solution short of changing the identity of the application pool.
While a reboot will resolve the issue temporarily, there is a Microsoft hotfix KB2545850 that offers a permanent fix to the issue.
i have created one web application in asp.net[.net 4 framework and visual studio 2010].Now i am running with IIS 5.1 version.When i running my application, i am getting the following error

I am also checked with EventViewer... It says

Description:
aspnet_wp.exe (PID: 1724) was recycled because memory consumption exceeded the 1221 MB (60 percent of available RAM).
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
I dont know how to resolve this issue? Is there any way to increase the memory consumption limit of RAM for my IIS.
Please guide me to get out of this issue...
Bottom line - you should debug the code to seee why it takes this much memory.
But to answer your actual question, yes, there is a way to increase this limit.
In the machine.config file there is a section named 'processModel' and by default it looks like this:
<processModel autoConfig="true"/>
If you change it to add a 'memoryLimit' value this will modify the percentage value used to determine when to recycle the process. For example:
<processModel autoConfig="true" memoryLimit="90"/>
This would allow the process to consume 90% of available RAM before the process was recycled. The default is '60'. You can of course also set a lower value.
This morning I have tried to load all my websites on my local PC that has IIS 7.5 and straight away i get a HTTP 503 Error.

So my application pool is not starting. I try restarting the app pool in IIS and I still get the error. When I look at the App pool I see that it has stopped. So I look in Event viewer:
Error: WAS : Application pool 'web80' is being automatically disabled due to a series of failures in the process(es) serving that application pool.
Warning: WAS : The Windows Process Activation Service failed to create a worker process for the application pool 'web80'. The data field contains the error number.
Looking around the web and stackoverflow, the problem seems to be caused by app pools identity being apppoolidentity. I changed this to local system and it works.
But why out the blue would this just stop working? I've read another solution that you need to provide permission to
C:\Windows\System32\config\Schema but I don't have a Schema folder.Could that be the reason why?
Really all I want to know is how do I get the application pool to reuse the apppoolidentity or where can I look to try things out? I could try re-intall iis but if I can figure out what causes this, I might be able to prevent it in the future.
Thanks
I just ran into this recently. In my scenario, I had the Application Pool Identity set to my Active Directory account under the 'Custom account' setting. Recently I updated my password so I just reset my password for the 'Custom account' accordingly and I was able to reload my application.
I am encountering a 503 - Service Unavailable error. I checked the event log and found this:
The Module name FastCgiModule path
C:\WINDOWS\System32\inetsrv\iisfcgi.dll
returned an error from registration.
The data is the error.
Note: Every time I try to visit my website, I found that the DefaultAppPool will auto-stop.
And also found this in event log:
Application pool 'DefaultAppPool' is
being automatically disabled due to a
series of failures in the process(es)
serving that application pool.
This is because your application pool is crashing more than 5 times in 5 minutes [default settings - Rapid Fail]
Instead of disabling Rapid Fail, you should consider taking Crash Dumps and try to find out the root cause. http://blogs.msdn.com/b/rahulso/archive/2006/03/02/what-is-a-crash-technically-in-asp-net-and-what-to-do-if-it-happens.aspx
