UART DMA Issue

I'm using MQX 4.2 on MK70 MCU. I use UART driver in DMA mode to receiver GPS data. I've found that if I pause the program in debug mode and resume it, the DMA will stop to receive any data. When the program is paused, the GPS will keep send data and somehow overflow the DMA buffer. Is there any way to safely close DMA UART and restart it?
