systemulserver creating swapfiles

Someone please help. Once a week around, my swapfiles in /private/var/vw/ folder keep duplicating in a matter of 3 min. Like swapfile 0,1,2,3,...26... It dosent stop untill all my ssd space is gone. I'll have 32gb free then i"ll have 25mbfree. My computer slows down when this is happening. So when I notice my macbook air slow down I ran fast to the swapfile folder and I see them being created fast. I opened activity monitor and I seen SystemUiServer taking up the most memory. When I forced closed it, the swapfiles stoped being created. So for some reason SystemUiServer is making a lot of swapfiles to be created. Does anyone know the cause of this. I've been trying to research why for weeks.
