Kent,

Can you do a listf of the (LFDS) examples you have in production and send them to the list so we can see an example of the sizes being built?

The Jumbo datasets (chunk files) came with 6.5 and were created as a fix for the 4gb limit that Amisys clients hit on a regular basis.

Thanks in advance
Joe Dolliver
