IIS Pool getting stooped when executing certain code

Metta Chittibabu

7y1.2k.NET

I have a mvc web site, also we have one DLL provided by third party.
We used this DLL by calling functions which are provided with in that.

At the time of calling one function, we are getting an exception and the iis pool is getting stopped.

We dont have acces to modify and handle the exception with in the DLL.

Simply we need to ignore the exception and continue with in the MVC application.

We need to skip the error and execute the following code as as usaully we write code in try catch blocks.
Kindly provide the solution.

Thank in advance

I googled lot of time but i did not find any solution to the above problem.
I went through the code and set the dll class objects appropriatly
then the calling method did not throw any exception.
Thank you for you replies

Hi Jignesh,

Thanks for reply.

I checked the given link below and the test server still getting stopped when calling function of the COM DLL.

The DLL we are using is some Interop COM level third party DLL

When i run this in Windows form application i dont get any error.
But when i run locally in MVC i get exception like ---- The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT))

But when i host in test server and run the same code (MVC) we are getting

Visual studio just-In-Time Debugger says 'An unhandled win32 exception occured in w3wp.exe(8080)'

Hi

try to run the application visual studio in IIS instead IIS express. You may get the issue.

When i check at local the exception i get handled by the catch block (some null refernce exception inside DLL).
But when we host in production server we dont get any exception handled by catch block.
and we have some alert box in OS says w3wp is terminated.

Thanks for response.
I checked the given link and am not sure is it about the some access permissions.
But in my case the site is accessing with out any problem untill unless we execute the code (which thows an exception).
