One clue here leads me to think your load curve is a pain in the a$$ for the solver. To keep the option turned on AND have it complete, try increasing the loads gradually on approach to the failing time step. Once it gets past that time, you can resume a larger time increment. But if it solved without it turned on with the original curve, then heck, you got the answer. Both options should reveal equivalent results.
The clue is If its turned off, the "max. incremental strain" value is used which might explain why it solves without issue. If its on, the max incre. strain is not used.
