The fact that there is a large difference between the "Oldest active"
and "Next transaction" value is a sign that you have a 'stuck' database
connection/transaction.

This active is preventing the engine from performing normal record
version cleanup operations.

A growing number of versions of records can slow down the system as the
engine must 'wade' through the older versions to determine correct state
of each record to be processed/queried.

You need to track down this 'offending' connection/transaction.
