FCPX Running out of Memory...pls help

I don't understand. I have a Mac Pro 8 Core 2,4 Ghz with 32 Gb of memory running Mountain Lion en Final Cut Pro X. I am working with one hour of videofootage from my Canon XF300 (XMF 1080 50mb/s converted to (FCPX Optimal Performance) ProRess.

I am working with the project for about an hour and then the memory-alert kicked in. I have been using a memory cleaner (which I feel I should not have too) and I had only 80Mb's left. How is this possible and doesn't OSX manage its memory itself?

What can I do?

Mac Pro, OS X Mountain Lion

It seems to me that, at least on OS 10.6 (which I'm still running), this RAM behavior has changed over the past several versions. Earlier versions (< 10.0.04?) I recall were very prone to not releasing RAM and requiring routine re-lauches to be able to work with any sort of efficiency.

Things definitely improved with subsequent updates – even though the old behavior would occasionally reappear..

Then I went through a stretch where I experienced similar problems to the ones you describe. Things would come to a crawl and re-launching FCP didn't do anything to free up the RAM; only rebooting would do it. After trying a number of , I've found that repairing permissions got things working properly again. I could then typically work throughout the day without that problem.( As a matter of course, I now repair permissions 2 or 3 times a week.)

Good luck.

I have never worked with permissions. Could you give me a basic instruction on what actions to follow? Much obliged

Sure. Launch Disk Utility. Select your boot drive in the left pane and click on the Repair Disk Permissions button below.

If the Show Details box is checked, you will probably see quite a long list of fixed permissions. And it will probably take several minutes to complete.

Good luck.
