Explanation of NT status code 0xC0000006 (STATUS_IN_PAGE_ERROR) is "The instruction at 0x%08lx referenced memory at 0x%08lx. The required data was not placed into memory because of an I/O error status of 0x%08lx."

Does the problem occur on multiple machines (different hardware)?

Otherwise this sounds like an issue for Microsoft.

What is the operation is the failure point on?

Are there third party libraries used?

If not already, consider implementing logging to a file with say SeriLog for instance which can assist with the issue.

Hi @RLWA32 , Yes this happen on multiple machines which are connected to network share drive as app is hosted on a Windows network share drive

Hi @Karen Payne MVP ,

What is the operation is the failure point on? This happens randomly on user machines in a day when they are using the app. App gets freezed and the user is unable close the app using task manager so they are having to restart their laptop. The app is hosted on a network share drive

The error mentioned above is captured from the system event viewer logs at the time of crash

Are there third party libraries used? No third party libraries are used

Have you tested to see if the issue occurs if the app is not run off of a network share?

Let me rephrase my question from

What is the operation is the failure point on

To what type of operations are being performed e.g. database operations for example etc.

And have you considered logging?

And perhaps you could share your code in a GitHub repository?

Otherwise its impossible to make an initial determination.

How does your "Winform application" related to ASP.NET/ASP.NET Core you tagged.

Hi @Sunny Sharma , Welcome to Microsoft Q&A,

What if you don't share your code? It may be difficult to solve your problem without giving any reproducible example.

It's probably not the answer you're looking for, but you should update to .NET 8. There are a lot of runtime changes between .NET 6 and .NET 8. Also, support for .NET 6 ends in 10 days. If there is any critical bug in .NET that you could report, they would want to know if it happens on .NET 8. So the first step to solving the bug is moving to the latest .NET.

.net 6 support ends in November and an upgrade will probably not fix.

This a common issue if you are running an exe off a file share. It generally means you got a network read error from the file share. I'd would have your network people check the stability of the network.

Yeah, you're right. I don't know how my brain swapped in Feb for Nov.
