Unusual Warning Message from Minuit...

Hi,

I have been getting unusual warning messages from Minuit from a new type of fit I am attempting. MiGrad runs successfully without any warning, Minos only gives the warning below and then exits with a status of "PROBLEMS", but then it claims the error matrix is accurate. How should I interpret this kind of output exactly?

Thanks!
