Instant-Grid

I am using IG 1.0.
I am running IG with a server and one client. When I run the POV Ray application, I monitor with Ganglia. I notice that free memory gradually decreases. This memory is not recovered after a the computation is finished. When I start another POV Ray computation, the free memory continues to decrease and the computation becomes very slow. Eventually computation ceases, nothing happens, and I must reboot the grid.

Is it possible that there is a memory leak in the POV Ray application that causes this? I hope it is not in the Globus Toolkit or your interface programs. Have you experienced this problem? Is there anything that can be done to prevent this?

Thank you for your attention to my query.
