[Clp] Help: incorrect solution from CBC

Hello,

I am attempting to use CBC v2.8.9, and it is reporting that it has found
the optimal solution, but the objective value that it returns is about 20%
higher than the result I get when using another solver (glpsol).  I did not
set any options, just used the defaults:

  "cbc model.lp"

When running glpsol, the only option that I used was enabling cuts:

  "glpsol --lp model.lp --cuts"

I have attached the .lp file with the model that I am trying to solve. I
appreciate any help.

Thanks,
Greg
