10. Stop chosen when the maximum time limit was reached.

This message appears when (i) the Solver has run for the maximum time (number of seconds) allowed in the Max Time box in the Solver Options dialog and (ii) you clicked on the Stop button when the Solver displayed the Show Trial Solution dialog. You may increase the value in the Max Time box (to a maximum of 32767 seconds) or click on Continue instead of Stop in the Show Trial Solution dialog. But you should also consider whether re-scaling your model or adding constraints might reduce the total solution time required.
