Comment (by pbelotti):

 This could be related to numerical issues. It would be very useful if you
 could send the instance that generated this, and even better if you could
 create a much smaller instance with the same behavior.

 Also, you may try to change settings, for instance turning off some the
 bound tightening procedures, by adding one or more of the following lines
 to the option file:

 {{{
 feasibility_bt  no
 redcost_bt      no
 aggressive_fbbt no
 optimality_bt   no
 }}}

 It is clear that the solutions differ, but I'd like to reproduce this
 problem. Thanks.
