# Error for parallel simulation

Dear users

I am planning to run my simulation in parallel. it is an optimal control simulation; however, after solving 37 iterations it stops and show some errors as follow. do you know what the problem might be?

Maybe a memory leak somewhere? Hard to tell without the script.
