How are we supposed to help you if we have no idea how you are using it?
Did you read the PORT documentation? Did you look at the control
parameters outlined in the function help page? Often times for me a return
of the initial conditions is an issue with either inappropriate tolerance
or having variables on very different scales.
Since you did not follow the posting guide (important part *'d below), my
only suggestion is to ?nlminb
