This is usually caused by faulty commodity. Check yours using CM. Some that have caused other users to have this problem are:
Rusty Rebar - 40ft - Load, KUID: 447922:1084
RoRo-Container_emtpy_pro, <kuid:121794:10167>
760mm Gleisjoch,<kuid:121794:10169>
If nothing shows as faulty, you can isolate the faulty one by disabling some of your latest commodities, then rechecking. If you do a Forum search for multiple industry you'll get lots of threads to check out.
