Not enough memory when exporting, even though there is still memory left in system

[RonRon98]

Hi!

Lately i've been getting many troubles with Lightroom, but one of them is Lightroom Classic won't export all of my photos, leaving out some un-exported with the reason of "Not enough memory" even though i still have some spare memory (definitely enough). I use the current latest version of Lightroom Classic, and was able to use it without any problem, like syncing to Lightroom CC on my phone. This is the full spec of my setup:

HP Envy 13

Intel Core i7-7500U

8GB RAM

512GB SSD

Latest Windows 10 Update

I already tried re-exporting, restarting my computer, temporarily disabling ThrottleStop,closing Chrome, and optimizing the catalog. none of them resulted in a 100% exported collection, even though previously i was able to export photos without a problem, no matter how much photo i'm exporting

Any kind of help is appreciated, and thanks in advance

Cheers

i checked when Lightroom was exporting, there was still around 1.5~gigs of RAM available (not cached).

yes, i've unchecked the GPU support from around a week ago (since i felt it was running slower when it was enabled

That Out of Memory error could be caused by not having enough disk space available or in your case, I think, not enough storage space on your SSD (as a SSD doesn't have any Disks).

What type of system are you using. Notebook, Desktop? And what kind, Mac or Win PC.

So with only one drive in or connected to your system 30GBs of available free space out of 480GB is an extremely small amount.

Try connecting an external drive and setting an export, any export, to go to that external drive. If you don't get that out of memory error you have found the problem. Not enough space on the internal drive.

That would give a "low on disk space" (or "low on storage space") error/warning.

If LR tries to use a very large amount of memory, Windows will allocate disk space for that virtual memory ("backing store", "swap file", "paging file").  So it's conceivable that LR is trying to allocate a huge amount of memory for the export (perhaps due to a bug) and the disk is running out of space.   With only 30 GB left on disk, it's plausible that LR would try to allocate that much virtual memory and fail because the disk gets full.  As soon as the export completes or LR exits, the virtual memory (and the disk space behind it) gets released.

It's easy to check if this is happening.  During the export, open Task Manager and sort by the Memory column:

While the export is going on, does LR's Memory increase much above 8 GB?

In Windows Explorer, you could also open Properties for C: while the export is running and see if the free space is temporarily getting close to 0:

I posted this elsewhere but I think it is of relevance here as well.

I did a quantitative test.  Such a test seems to be lacking on discussion pages re LR memory needs and performance.  My computer:   iMac retina 5K, 27 inch, 2019, Mohave 10.14.6.  LR is most up to date version of Lightroom Classic 8.3.1, Radeon Pro 580X 8Gb memory on the board.  I'll get into computer memory in a moment.  Working with RAW files from Nikon Z7 with typical size of 60 Mb. 

1.  iMac arrived with 8 Gb memory installed.  Did and HDR merge in LR with three images  Took about a minute.  Way too long for simple operation so I did not do subsequent tests with this amount of memory.

2.  Put in2 x 16 GB OWC memory chips via Amazon.  Did a test require HDR AND Pano merge - 18 images total (about 60-65-Mb each) with 3 images HDR set at each of 6 positions for the Pano.  Took 1m 38s for LR to create the Pano in preview mode.  Took an addition 1m 44s to creat the final image - a Pano with each segment an HDR image for total of 3m 22s.   Clearly much better than simple 8 Gb. 

3.  so I upped the ante going to 4 x 16 chips for total of 64GB.  Repeated same test as in example 2.  This time it took 1m 10s to generate preview in Pano mood.  A modes improvement of almost 30s.  But then I let it go ahead to create final image.  This took an addition 36s for a total of 1 46s ABOUT TWICE AS FAST AS WITH 32Mb.  Amazing.

@Jay, you have resurrected an old thread which ended a few months ago with the original poster’s last post indicating that the issue was not resolved.

It would be interesting to learn if he was able to rectify his problem and how if he did.

He has not logged onto the forum since.

Maybe his SSD has crashed!?

I have been creating DJI Mini 3 pro raw sphere photos (160 megapixels tif) and it usually ends with the error message of "some export operations were not performed". Did quite layers of adjustments and I had to trouble myself to "export with lightroom adjustments" to Photoshop, then save from there.

Now I found an indirect (yet the only) way that save some time, by exporting as "original" tiff into a folder with those that failed, use Adobe Bridge to go to the folder, select all the tiff file, right click "export to" -> "custom export". Options to save are just like Photoshop (image quality showing up to 12 without options to save according to file size). 

At least it can still batch save instead of manually exporting a few to PS to be resaved.

Hope this helps reduce some headaches.
