Debugging Rules in EPM planning

We have few Rules in EPM planning and budgeting - Profit cube which calculates the costs/revenue based on few allocation account drivers and then it allocates them across different products .
Now, I added a new allocation driver which is a percentage base and wanted to add that in the rules. Once I added it in the rules/scripts and ran it, it did not allocate any costs/revenue.

Hence, I wanted to debug my rules and find out what is going wrong, but the debugging is taking more than 10 hours and gives 'unknown' error on the 'Jobs' panel

I am not sure how to find a solution to this.
