Random AccessViolationException

KeithMacIntyre — Thu, 19 Feb 2015 18:42:13 GMT

This error occurs randomly, sometimes within a couple of hours of running the application, sometimes, over a day. From the stack trace it appears to be coming from the Runtime. The error occurs even when nothing is happening in our application

Re: Random AccessViolationException

Hi Keith,

Would you share what your app doing and which layers are you using? I tried to reproduce the issue with a Desktop app with just a base tiled layer and didn't see the error.

Thanks,

Asser

Re: Random AccessViolationException

KeithMacIntyre — Mon, 23 Feb 2015 20:12:37 GMT

I have been trying to reproduce it with a scaled down sample application without success.

It is happening in a scenario where I have one online layer:

World Imagery, ServiceUri="http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer"

We have a military message layer with a few minefields and wire obstacles.

There are multiple graphics layers with basic polygon graphics, but a large number of them

There is a graphics layer that has many custom rendered symbols that we set the symbol image using SetSourceAsync(stream)

When it crashes, the application isn't doing anything at all. I did notice when I had all exceptions turned on that I would occasionally get a WebException, so the runtime does seem to be accessing the internet even though the map extent hasn't changed.

Re: Random AccessViolationException

KeithMacIntyre — Wed, 25 Feb 2015 02:07:57 GMT

I am still unable to have it crash in my sample application, however, occasionally in our main application it doesn't happen either, although it does happen relatively often and on development and test machines. I wonder if it would be worth generating a debug version of the runtime for us with the .pdb files (source code even better), and we may be able to better understand exactly what part is causing the problem since it's difficult to reproduce

Re: Random AccessViolationException

AsserSwelam1 — Wed, 25 Feb 2015 02:13:36 GMT

I have been trying to reproduce it too with no luck even with the app running overnight.

Sorry I don't think it would be possible to do what you ask for, It will be better to contact the support regarding this issue.

-Asser

Re: Random AccessViolationException

AsserSwelam1 — Wed, 25 Feb 2015 04:48:46 GMT

Keith, are you using .NET SDK 10.2.4 or 10.2.5 ? because if you using 10.2.4 you should try to see if the same issue happening with 10.2.5 or not, there is huge stability fixes added in 10.2.5.

Thanks,

Asser

Re: Random AccessViolationException

JonDicken — Wed, 25 Feb 2015 16:41:53 GMT

Hi, we are also seeing Access Violation Exceptions occurring in our application, and unfortunately they are crashing the entire application. We saw this in 10.2.4 and have also seen the same issue since moving to 10.2.5.

The issue seems to occur most frequently when adding/updating labels on larger feature layers - so we presume this is in some way related.

Looking at the crash dumps from our application we can see it is coming from the RuntimeCoreNETDesktop dll. Analyzing the exception using WinDBG gives us the following info & stack trace:

Re: Random AccessViolationException

KeithMacIntyre — Thu, 26 Feb 2015 21:54:02 GMT

We are not using feature layers at all. It looks like your crash is coming from the License check function. That would be something that could be occurring when the application is doing nothing, like in our case. Another thing we have in our application is a second small overview map on the same window. Maybe having two mapview's in the same window could cause a problem?

Re: Random AccessViolationException

RexHansen — Fri, 27 Feb 2015 17:44:58 GMT

We have seen this issue before, but reproducing it has been elusive. Keith, you mentioned trying to create a sample app but were not able to repro. If you guys are able to provide a sample app to reproduce at some point in the future, please share.

Thanks

-Rex

I have not seen the Access Violation since we upgraded to 10.2.5, however, just this afternoon I have many times started receiving the following error and our application crashing:

We seem to be able to somewhat reliably reproduce this in a function that is deleting layers from our map. The layers contain MessageLayers, but it's not determined if that is the reason the crash is happening:

Exception thrown: read access violation.

Hei, Keith,

What version you are using and if you can you provide a reproducer?

Re: Random AccessViolationException

CharlieMatherne1 — Tue, 17 Jan 2017 00:38:20 GMT

I'm running into the following randomly:

System.AccessViolationException was unhandled Message: An unhandled exception of type 'System.AccessViolationException' occurred in WindowsBase.dll Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

A little background:

- I'm running Runtime v100.0

- The app is written using MVVM and Prism IoC

- There's a View (TwoDView) which has a MapView

- TwoDView has a ViewModel (TwoDViewModel) which navigates -- uses RequestNavigate(...) -- to a view (ThreeDView) which has SceneView

- ThreeDViewModel responds to the navigation and applies the camera (calling a controller, created to manage the SceneView using a WeakReference<>) passed via navigation parameters

- The controller calls SetViewpointCameraAsync

There is also a back button in ThreeDView to allow going back to TwoDView for selecting another 3D area for inspection. It seems multiple calls to SetViewpointCameraAsync is causing my issue...if I use SetViewpointCamera...no issue. Any ideas??
