Why is my FlexLogger Plugin leaking memory?

Hi All,

 

I'm hoping that one of you kind experts could spare a little time to take a look at a simple FlexLogger plugin that I created (based on one of the templates).

 

The issue I'm having is that when FlexLogger is running with this plugin, the memory usage (of the FlexLogger process) slowly increases over a few days. It was once left for about a week and the PC crashed.

 

Context:

 - The FlexLogger plugin reads a channel of 'Revolutions' and increments a 'Cycle Count' when the Revolutions reaches a target value and then goes back near zero. (Each cycle takes about a minute, so we're not looking at counting large numbers here).

 - We record in FlexLogger at 250Hz, and the test (ideally) runs continuously for a few months (with FlexLogger configured to split tdms files in 512Mb chunks).

 - I'm a beginner at LabView, so I wouldn't be surprised if I'm doing something like appending values to a variable every time Process.vi is run.

 

Would really appreciate any help you can provide. Let me know if you'd like any more details.
