Integration tolerances ode15s

Hi, I'm running code using the ode15s stiff solver, but am getting the following error message:
'Warning: Failure at t=6.513174e+006. Unable to meet integration tolerances without reducing the step size below the smallest value allowed (1.490116e-008) at time t. > In ode15s at 747'
I've tried reducing the tolerance but it hasn't had much effect - can anyone give me an idea how to solve this?
Thanks,
Rebecca

To resolve the symptom of the problem , you actually need to increase the tolerances, or reduce the allowed smallest step size as the warning indicated. Neither would guarantee to solve your integration problem as you need to consider your problem, choose the right solver, choose the right tolerance and step size.
