Previously created model which runs perfectly with 4.2a can't be solved by 4.3a

Dear all,

I created a model with 4.2a and everything goes smoothly. Now I'm using 4.3a, and the model doesn't solve. The solver settings are the same, the default MUMPS. Now appears the warning:

Warning: MUMPS allocation factor increased to 1.44.

and keeps increasing. Any ideas?

Thanks!

Try increasing MUMPS factor manually. Also One can try reducing Pivot threshold (say from 0.1 to 0.01).
