We have a farm of 5 Windows Server 2012 R2 servers, running IIS.
Under load, one website start failing every ~75 seconds and it keeps going on and on, until load goes down at night time.
Only thing we have to go after, is the message in the evenlog :

If I look at the "Workers" inside IIS, I just see a bunch of requests and the wait time keeps going up and up when I press F5 - until the process is crashing/restarted.
Any advise ?
The application is written in C#/VB, and uses controls from Telerik, saves data inside a Sql Server and caches via a distributed nCache running on 5 servers.
The application has been running for months without updates, other that patches to the OS regularly.

We have a sideload AppXBundle where we are experiencing the app crashing right after it shows the splash screen.
We install the certificate from our store association, double click on the appxbundle - App Installer prompt appears, and we click install. As mentioned, the splash screen shows, and then within a few seconds the app closes.
Here is the error message from the Event Viewer:

We have done quite a bit of research on the Windows.UI.XAML dll issue - I have uninstalled it with powershell, and reinstalled it. I tried updating it. Nothing seems to do the trick.
We have tried it with every compile version I can for the device (x64,x86,ARM,ARM64)
The target device is a Surface GO, but we have expereinced the app crashing on x64 desktops with Windows version 17143+.
We have this issue only on specific computers. 1909(build 18363.836) <- windows version where the app works.
If you need more information, please let us know.
I am trying to debug my asp.net , which calls a api (which is a 3rd party wrapper). On calling the below method it crashes.
private void RegisterCallbacks()
{
_instance.Callbacks.RegisterCallbacks(LogCallback, StatusCallback, BusyCallback, ExceptionCallback);
}
Here _instance is of that API. It crashes IIS and no error.. Any ideas what could be wrong?

My application crashed after running for some time.
I'm using .NET 4.6 on Windows Server 2012-R2.
Application is 64-bit.
I cannot find more detail about this bug code. I think I have all relevant updates installed.
This application has run cumulatively for thousands of hours before and this is the first time this particular bug happened.

I have a web site developed in ASP .NET MVC 5. It was working normally during last 9 month but since the web site got many active users (about 200 concurrent) it started to crash randomly in every 25~90 min. The strange part is that there is no exception in my log and the only exception that I could find is this in my event log:

Can any body explain me why it's happening and I can get more detail about exception and it's possible resolutions?
Update 1:
I found two hot fixes (https://support.microsoft.com/en-us/kb/2679415 and https://support.microsoft.com/en-us/kb/2640103 in Microsoft site which seems that is the case. One of them is not applicable for Windows 2012 :| the other one is not accessible to public. My emails to Microsoft site is also not answered!
Update 2:
Finally after hours and hours of research and code review I found cause of problem. In my code I was loading a DbSet from my Entity Framework db context. The records of database in that table was huge and because of this my app was crashing. And because I also had app pre initialization configured in IIS after crash again it started to load that DbSet again and here was a loop of crashing and crashing!
I have a Windows Service running in "Local System account" context.
I can start the service successfully, but after a few minutes it crashes. I get following error in the event log
What could be the possible reason, and how to fix this issue?
