Check that the cleanup server is running on a regulary base in oder to get the obsolete records physically deleted.

You might want to run the following query against the Process Instance table

Code:
select count(*) from fmc.process_inst where state=128


This will show you how many processes you have that are awaiting cleanup. If the number is quite large, I would say you are having Cleanup server issues, In fact since you indicate that the Cleanup server is running it should be very close to 0. Let us know what you are seeing and maybe someone can come up with an answer for you.

Since it appears that your cleanup server is running properly, the answer must be that you are just running more work and you have not reached an equilibrium for your RTDB yet.
