there seems to be a memory leak happening with Lightroom and or Photoshop in Mavericks.

While running heavy processes I'm able to max out the ram both programs use at around 8gb a piece, however, my activity monitor shows a continual growth in the amount of RAM being used. The File Cache section of the Maverics Activity monitor shows anywhere between 27-29gb of ram being used... and iStats menus calls it "inactive" memory.

There is no way to clear this without a restart aparently.
Is there some setting in Lightroom to control the cache size? I've already dialed back photoshops allowed usage to 16gb. but that didn't fix the problem

Photoshop allocates up to the limit you set in preferences, then reuses the memory. That is not a leak or bug, and we haven't seen any leaks in Mavericks - but it is possible that there are third party plugins that leak on 10.9.

I'm not sure about Lightroom's memory usage.

I thought the same thing. But I learned the File Cache keeps information from apps that have been closed in inactive memory so if you decide to open the app again and need to access that information, it doesn't have to be read from your drive. It's already in RAM. Which is much faster.

So if you launch another task that requires memory, it will be taken from the inactive File Cache pool as needed.
