Description
Selecting impeuler as solve produces the following message at every step:

In addition for large models, performance is degraded.
The problem seems to be related to all implicit fixed step solvers, such as imprugekutta.

When I have time to finish the SUNDIALS Upgrade to v 5.2 (see PR 796) I can resolve this as well.
