Is it possible to avoid integration tolerance error in lsqcurvefit

Hi,

I am working on parameter fitting of coupled non-linear ordinary differential equations.

Most of the times when I guess three initial constant values and run program in loop, it stops whole program (usually on second guess) and shows error i.e.

Warning: Failure at t=2.403593e+00. Unable to meet integration tolerances without reducing the step size below the smallest value allowed (7.105427e-15) at time t

Is it possible that I can skip that loop, and my program will go on third loop even after getting the error on second loop?

Thanks in advance.
