Hi,

when I run this:

%----------------
:-lib(eplex).
:- eplex_instance(prob).

main:-
   (
     for(_, 1, 100000)
   do
     solve(_, _)
   ).

solve(Cost, Vars) :-
   Vars = [A1,A2,A3,B1,B2,B3,C1,C2,C3,D1,D2,D3],
   prob: eplex_cleanup,
   prob: (Vars $:: 0.0..1.0Inf),
   prob: (A1 + A2 + A3 $= 21),
   prob: (A3 + B3 + C3 + D3 $=< 40),
   prob: eplex_solver_setup(min(7*D3)),
   prob: eplex_solve(Cost),
   prob: eplex_cleanup.
%----------------

with the OSI clpcbc solver, the memory of the process shoots up and away 
  until it reaches enormous levels. It was using 850MB of RAM and 1.5GB 
of  swap space just now when I killed it. Running in TkEclipse the 
'statistics' panel doesn't show any of this.

Is this expected, normal or an error in my code?

thanks,
Dan
