Getting a "Application has run out of memory" freeze when exporting video from CTA3 Pro.  Activity monitor says CTA3 is using 8GB of memory or so.  Installed the MAC patch as well, no help.  Never had this problem with CTA2.  Anyone else have this problem and/or have a solution?

(Retina, 13-inch, Mid 2014)
2.8 GHz Intel Core i5

8 GB 1600 MHz DDR3

Intel Iris 1536 MB

Remember the operating system uses some of that memory, the program uses some of that memory, and what ever you are doing is using memory also

I'm using iClone 5 that has higher RAM requirement than CTA, with 6GB RAM .

See Screenshot for RAM usage without iC5 Project Open , 28%usage. See Screenshot with iC5 Project Open, that has a lot of stuff in it. 52% usage.  
IMO you have sufficient RAM, to Run CTA. 
RAM usage depends upon the number of Running Processes & their size.

Do a before & after Taskmanager comparison, as I've done & see what you get,. Post Images.

Thanks for the reply. Here are screenshots of memory and CPU use before CTA3 is opened and while it is exporting a video.  

My Screenshots show with System Idle (0% CPU usage). 28% RAM usage without iClone loaded into RAM. 51% with. iClone loaded 1.3 GB RAM, which I'd expect to rise, when Exporting

Your Screenshots show approx 50% RAM usage, without CT loaded into RAM. .So there's a big difference & you have additional 2GB RAM.  Approx 80% with CT loaded & Exporting. CT's Memory usage exceeds the Total Memory usage, which is less than Total Memory available. So, the figures don't add-up. Either way, CT seems to be using more RAM than it should,  IMO..  Kernel Task is consuming 1GB RAM, but I think that's irrelevant to the prob.

Jeff Little is the Forum's CT Expert. Send him a PM. Good luck..  .

It would also be good to know the memory usage when the CTA 3 project is loaded before exporting. My suspicion is a memory leak of some sort where the memory increases with each frame exported without ever being released. In the graph in your second screenshot you can see the memory usage slowly going up, which shouldn't really happen.

That makes sense because it renders MUCH faster than CTA2 but when it gets into higher frame counts (over 500) it runs out of memory. I was able to render 9000+ frame videos in CTA2 without any problem. Don't know why it's doing what it is doing.

Seeing a MAJOR difference in memory use for export between CTA2 & CTA3.  I exported the same file with the same settings with CTA 2 and then with CTA 3.  See the screenshots below.  Eventually the CTA3 version will use up the RAM on my computer while CTA 2 exports fine.

Some good news regarding this issue.

We have found the problem that is affecting Mac users and this should be corrected in the 3.02 update due very soon now.
