[eclipse-clp-users] Decreasing stack size

Are there any ways to decrease stack size ? I already increased the 
available space alot, but the size is too big anyway.
My programm tries to call a predicate with two vars on every possible 
combination of the elements from two lists.
I'm using 
(findall(Result,(member(LegalX,LegalArrays),getSingleCombinationList(LegalX,NextArrays,Result)),List1)) 
for this (LegalArrays and NextArrays are the both lists)
Would maybe replacing this by something else (for loop over the arrays 
as example) decrease stack size ?
Would be happy about some generall tips.

best regards Christian
