Photoshop CC hangs on photomerge

L1ttl3J1m Oct 6, 2017 9:33 PM

Hi Everybody, I hope someone can shed some light on this...

So, I have a bunch of .RAW images I'm trying to make into a panorama. Photoshop is fine with up to 20 or so layers, but more than that it hangs.

Photoshop is taking about 45% of processor time and about 7 GB of RAM when the align starts. At this point, Photoshop is still responding. ie, I can grab the progress bar and move it around.

After about a minute or so, the CPU usage drops to 8 percent and Photoshop stops responding. The whole window stops responding, and it'll sit there forever, or at least 48 hours, which is the longest I've left it for.

I've followed the steps to disable the Adobe Spaces Helper and CEPHtmlEngine, increased and reduce memory usage, disabled the graphics processor and reset my preferences, disabled all the plugins, run Photoshop as Administrator and started Windows in safe mode and run Photoshop as Administrator in Windows safe mode

CPU: i7-5930k

RAM: 32GB DDR4 3400 MHz

GPU: 2 x nVidia 980Ti

OS: Windows 10 Professional

Are these full res RAW files? How big are they? I have a 3930K with 32Gb RAM and GT970, and that started to choke when I got a 50Mp Canon 5DS if I got greedy with photomerge. But try checking the root of your primary Scratch drive. I bet it creates quite a Photoshop Temp file with a 20 image photomerge.

Photoshop scratch disk also defaults to your boot disk. Should your Boot disk become full windows will go to pot. When this happen check the free space left on C: do not terminate Photoshop first. Photoshop also uses some temp space on C:

Longshot - but Photoshop does not play well with multiple GPUs (you say you have two). Have you tried disabling one?
Further info here (in paragraph 7):

The raw files are 10 Mb each. I've also tried exporting them to jpeg and TIFF before I do the photomerge with the same result.

Forgot to specify that: I've got the scratch file on a 3rd disk to both windows and the source files.
All the drives are SSD
Drive info and free space is;
C: (OS and Photoshop) - 137 GB
D: (Source Files) - 228 GB
E: (Scratch Drive) - 397 GB

Through a long and tortuous bunch of circumstances that I won't bore you with (except to mention that eVGA's support department is way better that Asus's), the two 980Tis have currently been replaced by a single 780Ti, with the same result.

Having exactly the same problem in Photoshop 2018 with macOS 10.12. Plenty of free RAM (>40 GB; 64 GB total), NVIDIA GeForce GTX 960 4095 MB, multiple SSD scratch disks and a rotary just in case with over 300 GB free.

Trying to combine 60 images that are about 5 MB a piece. File -> Automate -> Photo Merge. Have tried multiple configurations within Photo Merge, all hang at precisely the same (visual) way as the OP describes.

Also found another person with the same apparent problem, BUT while his worked after killing Photoshop a few times, mine will NOT even after more than 10 kills and reattempts. Link to the other person:
astrophotography - Photoshop stuck at Align Selected Layers Based On Content - Photography Stack Exchange

Just by doing a search on Google or DuckDuckGo.com for "photoshop photomerge hangs" gives a BUNCH of results that all seem very similar and we've been having this problem since at least 2013.
