We are running a 18 video screen installation with four networked computers. The three client computers are responsible for managing the display of 6 screens each, and this is done with several jit.qt.movie objects. The patch is too large to include, but below is a crash log. The activity monitor reveals what appears to be a memory leak which we believe is related to the jit.qt.movie object. When The jit.qt.movie objects are playing a single image with @loop 1, memory usage slowly increases until all RAM is used up and the patch crashes after around 1-2 days.

Has anyone else experienced this problem? Is this a known memory leak with jit.qt.movie? We know from other posts that jit.qt.movie has a memory leak when drawing directly to the screen, but we are not doing that here. The movie objects each are connected to a short series of gl objects. Are there any workarounds that will allow us to continue using jit.qt.movie?
