[Cbc] Cbc hanging

[Defeyter, Michael]

Hi John,

I've been testing Cbc with Clp to solve transport assignment problem, normally I use Cplex.
Cbc works fine on smaller versions of the problem but when I use it on the full size problem, it seems to hang after a while.
The same problem solves fine using Cplex.
You can download the mps file from this location (it's a 2.6Mb zip file, I was not sure how to upload it to the mailing list so I've put it on my website):

I solve this using the sample2 code with the preprocess option turned on, when I don't use the preprocess option it solves for a bit longer but eventually hangs as well.
Thanks in advance,

Regards,
Michael De Feyter
