I have LWSN set up on all machines and screamernetII works fine ,but occasionally just freezes on the odd job and just won't process them. This particuar instance, I've been using particlefx, collision objects, save PFX motion data and replaced particles with fxlinker. I'm just wondering if it seem to be freezing on the slightly more complex scenes. Is there a memory allocation issue to LWSN?

PS I'm on LW7.5 Mac OSX10.1.5 with 1.5GB of Ram

I've sent the scene to a render farm who run PCs and they have the same problem..
