Hi,

thanks a lot!  Yes, it looks like that there is in fact only very little RAM free.   This could be due to a Windows bug, I found some threads concerning issues with NUMA CPUs (I wonder if I have one?), for example here: http://support.microsoft.com/kb/2155311/en-us

Rendering in a separate process (for example using Queue manager) seems to be a good solution, which will have the additional benefit that I can further tweak the scene while the render is in progress...

Re the browser memory consumption: I usually have loooots of tabs open. Once when I closed a browser but took notes about the pages I counted more than 200... 

 

Best regards,
