labview will start to lag behind actual data aquisition

I’m currently using the USB-6001 with four sensors connected to it. I’m also utilizing the Write to Measurement File VI. The DAQ is running at 50 Hz for each channel, and so is the data acquisition. However, after about 10 minutes of recording, if I apply weight to a sensor, it takes around 5 seconds for the change to appear on the graph. Additionally, the graph occasionally stutters and rubber bands. I’ve used similar code at much higher data rates on other projects without encountering this issue, so I’m puzzled as to why it’s happening now. Is there an easy fix for this?
