The OpenEdge Hive

Progress uses the buffer pool which is the single largest memory usage by the database engine. Other than that, the 102B user each uses around 30M of memory. So for 1000 users, the system will use about 4G of memory and that is not a lot. The VST stats are part of the memory, they go away when you shutdown the database. VST has many parts, so if you are not careful, they might bite you when you least expected.
