you can find my previous dumps on your ftp (user ftp02137264). Also I've uploaded a new info. What I did:
1. Run Perf Mon and get thread(s) that consume(s) CPU in Veeam.EndPoint.Service.exe. It was not a single thread as I thought, but interleaved 4 threads - an educated guess is that it's a thread pool in your app.
2. I also got thread IDs for those threads. Actually I guess it's not very profitable as you already know where the thread pool in your app is located
What's actually interesting for us - what task(s) those threads are executing, but here I can't help much without version with extra logs.
3. I made dumps for Veeam.EndPoint.Service.exe and svchost.exe that consumes CPU.
4. Uploaded to your FTP.
Hope this helps,
