I just did a test and I see the same behavior.  Memory usage increases with each new image that is accessed, and the memory is not released.  I will have to do more extensive testing later, when I have time.  Win 7, 64-bit, i-7, 8gb ram, 90k image library.

Same over here.

Win7 Ultimate 64 Bit

8 GB Ram

When i access a folder with DNGs (converted from Nikon D3 RAW Files), i can pick/reject 40 - 44 photos (reproduceable) and then from one photo to the next everything (thumbnails and imagearea) is grey and i need to restart Lightroom. This never happened in Beta 2.

PLEASE ADOBE.. fix this fast

Not since I optimized my catalog (before that I did).

Hey!  That works!  Memory usage is in the normal and expected range after optimizing the catalog.  Who'd of thunk it.  Crisis averted.  Let's move on.

Thanks, Rob.

I consistently saw this behaviour during beta, and sometimes when LR was closed (for reasons given) the UI would completely disappear but Windows task manager would still show LR under "processes" (not "Applications") for up to a minute or more before the memory is released.

At first I thought LR may be "loosely" holding onto the memory with a willingness to let it go to other applications if needed, however I found it ground the whole system to a halt.

Disappointed this is still occurring in the released version.

Windows 7 (64) / Core i7 / 8GB Ram.

I am seeing LR quickly jump up to 1,200,000 K of memory usage and holds there between that and 1,700,000.   Definately a memory hog.

You must have never worked with SQL Server, then. Many programs that

use a db (and that's all your catalog is, a db file, using SQLLite) grab

as much memory as they can, to keep db operations in memory, for speed

reasons.

Actually I have worked extensively with SQL, but more from the developer side and less on admin.  Didn't even think about their database being SQL based.  What you said really makes sense now.

I have to correct a bit here. I had another login on my computer running a program causing the memory to be used at 100%, almost not using cpu. After stopping that and restarting my computer I am still using 2.5 up to 3.6 GB memory ( got 4GB) when using LR. Cpu is the same (up to 100%) and it is stuttering after a while.

But memory is not up to 100% as I said. I will not make this sound worse than it is

I have deleted all the preview files and rendered about 10,000 images of my catalog with ne 1:1 previews.

I still have the problem with the memory.
