Hi
The LiveCycle 8.utility is for removing all the data associated with a process. There are some other tables, not directly related to processes, that also grow large.
We are in the process of building a component that will purge these tables. This is not completely tested, and is available in beta only at this time - if you're interested in testing (backup your database first!), please email info-at-avoka.com
