Adobe Lightroom 4 have a memory leak problem. It allocates continously memory. You can look in the task manager, while lightroom allocate every second new memory. After a worktime of 3 hours it needs 6GB RAM on a Windows 7 - 64bit system. That is not acceptable for my usage.

Same for me. Also Windows 7 - 64bit system, and it certainly goes up fast.

Maybe an other problem : Video and library module : When choosing "capture frame" it does indeed count a new pile-up (left icon on the top left corner of the film preview) but no way to see them (open the pile etc) with the photos it works.
(sorry not the right translations as I work in french mode)

Can you be as specific as possible about what kind of work you are doing for the 3 hours? Do you see this problem even when not doing work?

Yes, I remember what I have done. I tryed out the new geo tagging tool. My pictures do not have geo tagging informations quite now. I have added this information manualy to the pictures for 3 hours. After that time period I couldn't work because all my memory was off.

But I saw the memory increas also when I do nothing.
I hope this information helps to fix the problem.

Same here.. but this time on a mac.
I was publishing DNG files to a backup location and the memory usage went up until the complete system froze.

Same here Win7 x64, Lr4 RC2
I ́ve just started off with Lr and I ́ve imported 17,000 files. Did developing of some and noticed the problem when doing lots of geo-tagging.
This is very hard to reproduce as the memory consumption seems "normal" to me while developing. I guess there ́s a lot iof caching going on, so no real problem.
In geo tagging the consumption *seems* to be more prominent to me. And in there I *guess* it ́s getting more when changing places a lot. Then again, maps are cached, so the term "memory leak" may also be not correct. Maybe it ́s just taking what it needs to cache as much data as possible.
If this is correct, it ́s not a bug. It ́s a missing feature of a limit that a user can put to caching, e.g. set it to 4GB.

Sorry for so many "guesses", "maybes"...but I also didn ́t find any steps so far to clearly reproduce obviously faulty behaviour (but will try;-))

I also have this memory leak. LR4.1 RC2. Win 7 64 bit.

I too have the problem and reported it in a different thread at http://feedback.photoshop.com/photosh... where I have details including a graph of memory usage over time. Lr memory consumption continuously climbs even when the whole system is idle. But it skyrockets when alternating between keywording and geotagging. That continues until I'm told I have to shut down Lr because of low memory even though it is the only application running in 10GB.

I have the same problem. I'm using LR4.0 and after just browsing images for about 30 minutes, window comes up with the message "system is low on memory and need to close Lightroom 4.0".

Spec Win7 64bit, 6Gb Ram, Q6600, Nvidia 8600. Not a new computer anymore, but it should be good for LR. I'm doing hours of heavy load work with Photoshop CS6 and never get any problem.

To report a non-leak case, I have installed RC2 since released and I normally do not shut down my iMac unless software update ask me for, and I keep LR open for long times, until I finish editing a session

LR4 RC2 spent opened 5 days (iMac ask me to reboot to install an update 3 days ago after 46 days from last boot, in which I have used LR4 repeatedly)

In no scenario I have any problems with memory leaks. I have a 16GB system and I use Activity Monitor all the time in the dock with the memory usage.

Note: I do not use geotagging. Develop module, tags in library, print, are the most used features

I understand the issue is with W764, but as one posted about mac, I just figured out send my two cents

Mine doesn't leak, too much, during "normal" (read: mostly editing) use, but it consumes too much when doing whole catalog ops, e.g. via plugins.

I have to divide my photos up and do one chunk at a time, for just about anything and everything I may think to do to the whole cat-worth of photos...

If I don't divide to conquer, my computer will slow to a crawl and need to be reset...

Twice today, W7-64 warned me that I needed to shut down Lr 4.1 RC2 (it had consumed 90+% of my 10GB). Before I could do so, W7 crashed. Rather than a BSOD, the display just went black and I couldn't use Alt-Tab to get to another app, nor could I use Ctrl-Alt-Del to bring up the Task Manager ... or at least I couldn't see if anything was happening. I just had to do a hard shutdown of the computer. Ugly business!

THIS IS OUT-OF-SEQUENCE. IT WAS ACTUALLY POSTED SEVERAL WEEKS EARLIER BUT, WHEN ADMINS COMBINE THREADS, IT SETS THE TIME ACCORDING TO WHEN THE COMBINING WAS DONE, NOT WHEN IT WAS WRITTEN.

I've been using Lr 4.1 RC2 for a couple of days under W764 with 10GB of memory. Memory usage before launching Lr is about 20-25%. When Lr is running, it's about 40-45%. But as it runs, it slowly increases. All I'm doing is importing, assigning keywords, and draggiing/dropping in Maps to geotag. memory usage creeps up over a couple of hours to 65-75% and then W7 tells me I need to shut it down or risk losing data. This happens every time I run Lr.

Lightroom 4 (up to RC4.2) has a memory usage error as reported by others. On a 32bit Windows 7 machine with 4GB memory it fails or slows dramatically after a period of editing but problem is cured when application is closed and re-opened. Problem applies with JPEG, NEF and CR2 images. Some operations fail like export 'out of memory', some loop (undo edits), some execute with errors (prints blank pages).

I posted this in a different forum, but this one seems more active.

I have a win 7 64 with 12 GB or ram. After one day of use lightroom is getting sluggish and is reporting 1.9GB of ram used, but immediately upon shutting down lightroom 7GB of ram are released.

I would like to update with the experience with final release 4.1 for Mac

I am observing increase in inactive memory with Lightroom is opened, even idle.
This was not happening before

The inactive memory increases until all free memory goes out - I have 16GB RAM and the memory left is around 300MB

Being inactive memory, OS X will use it for other processes if necessary, but that is a new behavior I didn't noticed with RC4.2

I have 4.1 and can report the same slowness/memory leak issue as above posts. I exclusively use the Develop module with lots of selective brush adjustments, spot healing, the usual stuff.

I find the longer I use LR, the slower it becomes and more memory it chews up. It never releases memory until u close LR. I have 8GB RAM and LR used up all available memory (nearly 7GB), forcing Windows to start using the swap file.

My specs: Intel Core i7 @ 3Ghz, Win7 64bit with total 8GB RAM, 1TB HDD (7200rpm), 1GB Nvidia graphics card.

Attached a screenshot of Windows Task Manager so u all know I'm not bullshitting you :)

This thread is a bit old but thought I'd chime in that Lr 4.2 on my Win 7/64 system experiences huge slowdowns and excessive memory consumption after 30 minutes or so of light editing and browsing of photos in the develop module.

I have quad-core, 20Gb RAM and Lr typically goes up to approximately 4GB of usage. I am NOT doing any heavy editing or geo-tagging. Despite this, CPU will spike between 75 and 100% with regularity.) My capture NX2 uses about 5GB but runs rings around Lr in speed at the moment, so I don't think it's a pure consumption issue.

Interestingly, when I restored my catalog from backup, trashed and recreated my preferences and rebuilt previews Lr ran beautifully for a few weeks. Now that the old problems have returned I do not intend to go through that again. I fear that the program is beginning to suffer from progressive bloat. Lr 3.6 performed so much better. Too bad that didn't last too long.

It is now 2013 - I have the same problem with Lightroom 4.3 64 bit and Win7 Home Premium. Nothing special - importing files, geo-tagging and then selecting to edit some files in Photoshop Elements. Machine is an i7 with 6GB of memory. Seriously, Adobe, you need to create a patch and fix this problem!

Yep - still leaky. Just working on a photo, sometimes it ramps up to 9X%, doing nothing special that I can ascertain - danger Will Robinson... - if Lr not shutdown in time, the whole system will become unresponsive (generally accompanied by incessant chunking on the hard drive, presumably trying to run with virtual memory since real memory is gone).

It seems to happen more often (but not only) when it encounters photos with lots of locals applied.

I have seen lots of memory leaks too and they continue in LR5. Particularly I see issues with complex use of the brush in the Develop Module and almost any use of the Publish Services. I typically Publish and then restart. LR5 does not seem to improve any of this.
