USART comm between 2 boards with debug break points

I am using two STM32F407x boards.

board 1 sends a data packet continuously
board 2 parses data continuously

In order to see if the data is being parsed correctly, I am adding break points in the code. The problem is that this seems to be making the USART act erratically. It will seem to fail to hit break points or sometimes receive the wrong data.

I am fairly certain that I have both set up in the same manner. Any ideas as to what is causing this behavior?
