Heap usage profile fails to capture traces on repeated WPR recordings of the same process

Hi.

I am trying to fix memory leaks in my server application running as a Windows service using WPR and WPA.

I have a strange problem that my recordings only succeed only once just after I restart the server.

On every repeated recordings done without restarting the server WPR fails to capture any heap usage trace events.

This is a big problem for me since I would like to be able to record consecutive traces in periods I notice that memory grows.

I tried this on both Windows Server 2012 and 2016 machines but have the same behavior.

Do you have any idea what should I do to enable many repeated heap usage traces on the same instance of the process?

Thanks,
