title: WPF application crashes
body: <p>There are some crashes in a WPF application and I can not figure out the cause. In development I can not simulate the problem, it occurs only in production and in random situations. The application has several Timers and DispatcherTimers for different processes.</p>
  
  <p>Any suggestions on how to find the locking point? Or at least have some clue where to start analyzing the problem?</p>
  
  <p>Is it possible to know which method is locking the UI thread?</p>
  
  <p>Thank you</p>
