You replied with a private message. This does nothing to help others learn and comment. You indicated if you turn off the recirculation pump, you don't get water at the furthest location...I can see a really long time to get hot water, but if it truely stops water from getting there, you have a bigger problem.
As to whether just turning the pump off will hurt anything...no, it should not do anything except lengthen the time to get hot water at the end of your line.
