Network Stream memory piles up for fixed size of 1D DBL array of data

[Priyadarsini]

Hi All,

I use Network Stream to communicate between a VI & Exe - here VI is the writer and Exe is the reader. While creating the endpoint I give a minimum buffer size, say 100. But when I actually write to the stream I input an array of DBL of size 1000. As per the documentation this situation is to be handled by LabVIEW & I am also reading all my 1000 values. But the memory keeps piling up for the Exe while LabVIEW memory is fairly constant or not increasing at a noticeable rate.The same happens even if I give the buffer size to be same as the expected array size.

1. So even though I use the scalar data type as recommended (array of numeric) and the array size is also fixed for all transfers, why does the memory keep increasing?
2. Why is the memory increasing on the Reader side?

Any earliest reply is really appreciated.

Thanks,

Priydarsini S

-Are these both vi and exe running in same machine or different?
-do you mean memory usage meaning RAM memory? Or you observing any changes in cpu usage also?
-Available Elements for Reading property is used by the reader endpoint to return the number of unread elements that reside in the endpoint buffer. So can you check with this property and see how many elements are pending to be read? And for write also?

It could also be something not entirely related to the Network Stream.  Code would help a lot here for us to help diagnose your issue.
