.Net Core 3.1 Based Stand alone Web API is crashing with stack overflow exception due to the KERNELBASE.dll

Mohammad Bhaji 1

I have a .Net Core 3.1 based Web API created as a standalone package MyApp.exe and installed in a windows based container. Only in certain container instances the WebAPI process MyApp.exe getting crashed randomly. From the application it is not logging any errors. But with the crash Dump got the below information. In the Web API, I am not using any recursive calls there is no possibility of stack overflow exception should occur. What could possibly be the reason for the crash?

Note: I am able to see some crashes of powershell.exe with the information of KERNELBASE.dll in the same container

The Dump file content Unhandled exception at 0x00007FFB2B4456CE (KERNELBASE.dll) in MyApp.exe.dmp: 0xC00000FD: Stack overflow (parameters: 0x0000000000000001, 0x0000002E8983EF78).

Is it possible you have a property that uses backing fields? Take this example

     public string FirstName
     {
         get => firstName;
         set
         {
                if (string.IsNullOrWhiteSpace(value))
                   throw new ArgumentException("First name must not be blank");
                firstName = value;
         }
     }
    private string firstName;

If you accidently change firstName = value to FirstName = value in the set it will cause a stack overflow

HI @Ken Tucker . Thanks for replying.

We are not having this type of code handling anywhere in our project. My doubt is it is not just my application even powershell app also got crashed with the logs stating that KERNELBASE.dll with the similar type of issue. so is this a common bug in microsoft components or is it specific to .NET CORE.

No it is not happening now. Only that time and also in a single container alone it happened. So any idea what could be the reason?

@Prabhu Janakiraman For such intermittent issues we mostly need logs and other details as well which can help us to understand the root cause of the issue .Since the issue you faced was more than a month back the logs in your tenant won't have those stored as logs are saved for only 30 days that too depending upon type of subscription or License.

For now what I can suggest is if you face this issue again you can directly drop me an email at AzCommunity[at]Microsoft[dot]com referencing this thread as well as your subscription ID. Please mention "ATTN: Preeti" in the subject line so I can directly engage you with our internal team and we can help you out better.

Do let me know if I can be of any further help!!!

Thank you for your cooperation over the matter.
