I have a server application that uses ~30GB of memory. I can attach dotMemory to it but when pressing "Get Snapshot" I see the progress bar hanging (no activity for >20 minutes) in the "Saving snapshot" stage. I tried profiling the app during startup where memory usage was lower (~2GB) and this completed successfully. I reproduced this 3 times - the first two using remote profiling the last running locally.
I am running dotMemory 2017.1.1.
I can provide additional details if needed.
