the integration fails.

Please make a small program that demonstrates the problem and send it to the list. Otherwise it's hard to say what the problem is.

Can someone please say something about which is the preffered stiff solver?
bsimp or msbdf?

Generally speaking, the efficiency of one stepper over the others can depend on the case, so it is hard to give any general advice. If the system you are trying to solve imposes no constraints on the selection of the stepper, then you can test each stepper and see what is most efficient in your case.
