Merged

This conversation has been merged. Please reference the main conversation: Lightroom/Camera Raw: Cannot merge panorama after updating to 10.14.6

Hi,

I noticed memory leaks during in HDR merging. Memory consumption goes so high that app stops responding and has to be killed. Issue is 100% reproducible.

Steps to reproduce:
1. Get 4 set of images for HDR merging (each set containing 3 DNG images, 6000 × 4000 pix, ~30MB)
2. Perform first HDR merge, observe RAM consumption
3. Perform next merge

App stops during third merge on my MacBook Air. I would expect memory to go down after processing the first set.

I can provide the DNG files if needed.

For reference, this seems to be the same issue as Classic: Lightroom Classic: Cannot merge panorama in 10.14.6

Wojtek,

I would like to get your sample files. I am not seeing higher than normal memory consumption on merges on my machine.  Could you package up the four images and send them to:

Hi Rikk,

Thank you for looking into my issue.
Files are too big for email client unfortunately.
I uploaded them on Google Drive, please find them here.

The memory consumption goes up after each HDR merge.

File 2 in Set A is corrupt but it still merges.

I merged each set back to back. Memory went to 7.28 GB during the third merge. Or about 45% of Ram. It drifts back down slowly after the last merge is done. 

What is the ram on your Air?

This is likely related to a different thread. I am going to merge you into that conversation.
