I have also seen this problem, but the wierd thing - on my 2 Gig 3.2Ghz P4 at the time of out of memory error happens.. only 1 Gig of ram is being used. There is no problem with VM, I have almost 500G of storage space on this system and it should be way under 1/2 full. I have notice the out of memory error happening when populating an ecosystem. Maybe Vue should have per ecosystem limited of objects.
