Memory Full error.

[AlPal]

Hi, I am getting a gradual increase in system memory usage, that eventually results in a Memory Full error while writing a small (<Mb) file. If the error is cleared, the program continues, but eventually the error re-occurs.

Thanks for any suggestions.

You are leaking memory -- which means something you wrote is not right. Can't tell more without seeing your code. Make sure you are closing all your references.

Thanks,

I will talk to the programmer to see if he understands what you said, as there is probably 10k lines of code.

Well if there are lines of code, you are on the wrong forum. LabVIEW doesn't do lines of code...

[AlPal]

Yes, I know. I was just trying to give an idea of the program size. There are ~50k VIs.

The zip file of the program is 300Mb.

The biggest memory issues I have seen deal with dynamically building arrays inside of loop, usually with the Build Array and Insert Into Array.  The alternative here is to initialize an array to the size you would expect and then use shift registers and Replace Array Subset to update the array.  The Build Array causes memory allocations with each call.  The replace array subset does not as it work in place.
