why my vi has an execution times increasing?

[br]

I have a vi with multi access to Daq board using Nidaqmx  lib VI.  This vi must work 24h/day . But the execution time is getting bigger and bigger for example at beginning the executuion time is 3sec after 2 weeks it is 30 secondes?

I suppose it was a Pb with Nidaqmx sub vi but i m not sure

Have an idea?

cheers

It's hard to answer this question without seeing the VI.

However I assume you have some "growing Arrays" in your code.
