Yes, I have already done all of that. I did choose a time with the least amount of connections. There is one that comes from a java source that is open all the time. This one pumps data in at an almost constant basis. This is the one that I am having difficulty with. I have already chosen only the tables and indexes are large. I am not performing this on tables that never change or that are fragmented below a set percentage.

Thank you to everyone that replied
