Memory Leak with LV 8.6.1 when opening reference in Real Time project

I have found what appears to be a memory leak within LabVIEW 8.6.1 when I open a reference to a VI that is targeted in a project to a LVRT application. It seems to only happen if the application has a real time timer module and if the front panel of the vi is not opened. I am using Windows XP on the host machine. The memory growth is about .5 MB of memory for each reference call. I have included a project along with an example vi that will grow the memory usage on the host machine. This only happens when the vi on the RT machine includes a vi from the RT Timing pallet. To recreate the problem just open the project and run the File load on RT try1.vi on My computer. The RT does not have to be connected to the host to see the memory growth, but hte front panel of Untitles 1 needs to be closed. It is easier to see the growth using process explorer from sysinternals so that you can view the memory usage of LabVIEW on a graph.

I ran this on my system and found the same memory leak behavior. This was reported to R&D (CAR #196547) for further investigation. If you leave the RT front panel Open or if you remove the timing the memory leak goes away.
