The process was terminated due to an internal error in the .NET Runtime at IP 00007FFB31E21DCB (00007FFB31C90000) with exit code c0000005.

Question

Hi,

I am getting this error almost daily.

Application: w3wp.exe
CoreCLR Version: 4.700.20.56602
.NET Core Version: 3.1.11
Description: The process was terminated due to an internal error in the .NET Runtime at IP 00007FFB31E21DCB (00007FFB31C90000) with exit code c0000005.

And I think this error is causing the following error:
Status(StatusCode=Unavailable, Detail="DNS resolution failed")

Please can someone help me with whether this is an issue with .Net core 3.1 or maybe dotnet runtime?

Answer 1

Hi,Salah

Exception code c0000005 always caused by the access denied. That means your program is accessing a memory address without the permission.

For example,

1. you read an array of length N but you read N+1
2. try to access memory that has already been deallocated.

You should debug to check the exe.

Or you can follow this link then check whether it can work:
