[Ipopt] re. local minima

I am relatively new to optimization. I am optimizing 2 variables for a
trial and noticed that in my problem, occasionally the objective function
falls into a local minima, (even though there were sort of global minimum
 achieved in the previous iterations) and stays in this for a very long
time say, around 1500 iterations ( believe its trying to find a new search
direction and step size). Is there any settings I can use to avoid this and
save computational time.

Looking forward to your kind help.
