Free Container Pages
The number of free container pages in the liveCache basis layer is the number of pages where free space exists for the persistent saving of objects.

The number of free container pages is NOT the number of completely free pages.
As long as the number of free container pages is larger than zero, no new pages are requested when creating new data within a container.
Pages are only deleted if they are completely empty. This behavior explains the following circumstances: although a large number of objects have been deleted in a liveCache database instance, this space does not seem to have been released.
The free container page can be displayed from the liveCache Assistant in the Class Container user menu.
