I have a model that runs for 3000 seconds. When the simulaiton hits 1571.55 seconds, Simulink starts throwing warnings such as:
E3dof' variable sample time for tid 5 has a nextT of 1571.5500000000002 which will cause the solver to take a step smaller than the minimum step size of 5.5830895462349872e-012 at time 1571.55. Warning: Timing engine warning: In the model 'DSE3dof' variable sample time for tid 5 has a nextT of 1571.6000000000001 which will cause the solver to take a step smaller than the minimum step size of 5.5834185166791293e-012 at time 1571.5999999999999. Warning: Timing engine warning: In the model 'DSE3dof' variable sample time for tid 5 has a nextT of 1571.6500000000001 which will cause the solver to take a step smaller than the minimum step size of 5.5835961571778936e-012 at time 1571.6499999999999. Warning: Timing engine warning: In the model 'DSE3dof' variable sample time for tid 5 has a nextT of 1571.7 which will cause the solver to take a step smaller than the minimum step size of 5.5837737976766596e-012 at time 1571.6999999999998.

I receive these warnings only in Simulink 6.4 (R2006a).
