The heap dumps show around 300000 elements loaded by the inspected pages. We cannot do much when the inspected pages are that large. I have added a warning when the number of elements reaches 100000. This warning tells the user (s)he may run into OutOfMemoryError and suggests closing of the page/stopping of the page inspection.
