Sun 15 Oct 2017 07:13:04 AM UTC, comment #1: This error seems to originate from a very rare case where msadams operates on method order >2 and then carries out two consecutive failed steps, both of which decrease method order. In normal operation solver is reset after three consecutive failed steps, but this special case of two method order decreases raises error before resetting happens. Solution strategy: Add reset also when two method order decreases happen.
