Showing frustration is ok if you do it right. If you are frustrated and you start complaining, then the manager will either think you are not capable of doing your work, or the manager will realize that you have way too much work. So it is important how you complain and how you show your frustration.

Complaining about someone else is not good. But if you are so frustrated and you have to tell your manager, take a deep breath, calm yourself down, and say something like my example as calmly as you can.
