MinAbsDifference, MinRequiredResources not working

[sabdulla-ahc]

I'm unable to utilize the MinAbsDifference OR MinRequiredResources in order to calculate optimized number of call center agents per shift. After setting all the parameters, once I try to run the optimization solver, e.g: difference_solution = difference_scheduler.solve() the kernerl dies and has to be restarted. I've tried various set-ups and as little as 1 day with both MinAbsDifference and MinRequiredResources with 0 successes. It's driving me crazy, am I missing something here?? Please advise.
