Problem Note 57429: The QP solver in PROC OPTMODEL might terminate abnormally and issue an arithmetic exception error
 |  |  |  |  |
In the OPTMODEL procedure, the following error might occur in the QP solver if the model is actually infeasible:
ERROR: The solver terminated because of an arithmetic exception.
It might be possible to circumvent the problem by changing the feasibility tolerance level using the STOP_PI=, STOP_DI=, and STOP_DG= options in the SOLVE WITH QP statement. For example, the following code relaxes the default 1E-6 value for each option:
SOLVE WITH QP / stop_pi=1e-5 stop_di=1e-5 stop_dg=1e-5;
