Simulink model developped and running well in 2017b, exceed Jacobian elements allowed in memory in 2018b

In 2017b, the model is running well in ode23t, however, when passed to 2018b, it doesn't work with the error that the maximum Jacobian elements exceed which is allowed in memory.
When changing to an explicite solvor, an oscillation shows up where it should be stably waken to 0.

This happens when the solver is kept as 'auto'. Using auto solver will fail to select the right solver if the number of jacobian elements is high. Selecting a solver as 'ode45' can help to solve the issue.
Please note that you might need to use a solver other than 'ode45' based on your model.
