I have a situation where my application sometimes fires during the pause / resume process. The scenario is as follows:
- The application is working fine.
- The user exits the application using an action, for example, by pressing the "Start" button, using a set of files or launching another application. At this point, the pause procedure is performed. According to all the studies and journals that I create, I know that the suspend event handler runs without errors. A deferred object (part of the suspension process) is designated as completed. Typically, the pause process takes 200-500 milliseconds.
- After a short period of time, the user returns to the application.
- OS displays the message "Resume ..." for a few seconds.
- From time to time (rather difficult to reproduce) the message "Resume ..." disappears, and the OS startup screen is displayed - this indicates that the application crashed. According to all the studies and journals that I create, I know that the event resume handler is not called.
- If the application crashes, the OS creates an application dump file.
Taking the application dump file and examining it with WinDBG, you will see a call stack similar to the ones I have at the end of the message. I grabbed 5 such dump files, and they all show the call stack that Windows_UI_Xaml!DirectUI::DXamlCore::OnAfterAppSuspend . After this method, I have either something that shows CoreClr!CLRServicesImpl::FinalizerThreadWait , or something that shows CoreClr!CLRServicesImpl::GarbageCollect .
Questions
- Based on these calls, can I assume that after the successful execution of the pause event handler, the application freezes in some main part of the framework?
- Is this an indicator of an error in the structure that manifests itself in some rare cases associated with the suspension process? Or could it be caused by an error in my code?
- Does anyone have the opportunity to share ideas based on the tables presented here?
Here are two examples of WinDBG analysis of two of these dump files:
