User-AOS crashing on ntdll.dll

Posted on by Berthil 204

Dear community members,

I'm having an annoying issue where multiple times our user AOS'ses are crashing. When I check Windows Eventviewer I see an error on ntdll.dll. In cooperation with our business partner we have managed to create an analysis dump and send it to Microsoft but they couldn't find anything. :(

This is the error:

Faulting application name: Ax32Serv.exe, version: 6.3.5000.267, time stamp: 0x58196e47

Faulting module name: ntdll.dll, version: 6.3.9600.19153, time stamp: 0x5b93ffa7

The weird thing is that only our user-AOS-es seem to crash, so it looks like a user initiated action which causes the AOS service to crash.. But which one..? I've thought about clearing the user-settings, but every user has customized nearly every form to their liking so I want that to be a last resort.

In relation to the problem I've got some questions:

1) Is it possible to delete the user files from the APPDATA folder without clearing everyone's user settings? (Query's, GRID-settings etc.)

2) Can a Windows .Net 'Preview of Quality rollup' cause an AOS service to crash? http://support.microsoft.com/kb/4462502 . The support page tells that there are problems with SharePoint workflows though..

3) Any more ideas?

Our Business partner is advising to upgrade our kernel but doesn't it seems a little drastic?

    It's strange that Microsoft support engineers weren't able to extract any information from the dump, but you can take a look by yourself. At least, you should be able to find the call stack leading to the exception, which may tell you which action was responsible for the crash.

    Upgrading AX kernel isn't anything drastic. In fact, it's recommended that you always run on a recent version of kernel. If you use an old kernel, you're risking that you'll run into problems that have been already fixed in newer kernel versions.

    Dear Martin,

    That's indeed somewhat strange that Microsoft can't find anything. We're planning a kernel upgrade very soon. But till then we're stuck with this issue.

    This is what I can find in the debug analysis. It also says something about a time-out.. not sure if this is before or after the AOS-crash.

    Exception code 0xc0000374 means heap corruption, therefore it's what the analysis talks about in "... has caused a corrupted heap exception (0xC0000374) when trying to perform an unknown operation on memory location 0x00000000 on thread 60".

    Follow the link for thread 60, it should show you the call stack.

    I have uninstalled two Windows Updates regaring to .Net updates:

    - KB4459941

    - KB4459935

    After the uninstall our AOS'es haven't crashed and the .Net warnings and client time outs in the eventviewer are occuring a lot less. 

    Fingers crossed if this has solved it.

    Just to echo the advice on kernel update - this should be regular practise- and also ensure your clients and server are on the same kernel version.

    I understand. The kernel is scheduled to be updated.
