Comparing two full dumps (first dump when app mem was 5 gigs high, second dump when mem was low 2gigs), i see memory LiveBytes/LiveInstances goes down to 0 i.e. delta = total number in the first snapshot. Can you explain why this is reported so?

If the Live instances/bytes value is zero, the profiler has most likely failed to import the memory dump. If the memory dump is created at a bad time, e.g. when instances are being moved in memory by the garbage collector, then the profiler may not be able to retrieve information about managed instances. Unfortunately, the profiler does not currently detect this, and will present the imported dump as an empty snapshot. There will always be a risk that a memory dump cannot be imported by the profiler, but we will try to detect this and at least present a message to the user in a future version.
