We have used dotMemory in the past with the same application with no issues.
But lately (using the latest dotMemory version) we have “occasionally” see this error when taking a snapshot: FR::Unexpected integer element type

 

Our application is in WPF.

Hi,

Could you please collect Profiler Core logs with additional diagnostic information as described below:

  • Clear %temp%\JetLogs and %systemroot%\Temp\JetLogs directories
  • Launch dotMemory and open the Profiling tab in the menu on the left
  • Press Shift+Ctrl+Alt+F11
  • Check Enable logs
  • Put 2749048496387 into the Logs mask field or check the checkboxes shown on the attached screenshot manually
  • Click "Save"
  • Reproduce the issue
  • Close dotMemory
  • Archive the contents of %temp%\JetLogs and %systemroot%\Temp\JetLogs and attach the log archive to this ticket.

You can upload logs to our ftp.

By the way, 
2022.3.3 dotMemory works fine for the same app and doesn't show any issue.
