Something is indeed wrong, and I have experienced similar problems in the
past. What version of CPLEX and which version of Sage are you using? I am
using IBM ILOG CPLEX 12.5.1.0, and Sage 5.12 on Fedora Linux 19 and Sage
5.10 on Fedora 13.

What other information can I give to help track this down?
