William,
Thanks for the reply. After replacing the system file path indicator with a string indicator, the memory leak went away. My application has been running at a steady memory now (it has actually declined from when it started). I am not opening references within that VI nor am I using DAQmx within that VI. I am doing that in other subVIs, but the memory leak occurs in the vi containing the file path indicator. I find it bizarre that a file path indicator would cause such memory leakage over time.
Thanks,
