I am attempting to create a panorama from 8 x 24 mb Canon Raw files. They were taken on a Canon 5D Mk III using a 24mm lens. The software creates the preview but once i attempt the merge I am advised there is a software problem and the program closes. I am running the software on a laptop with 32 GB RAM. So memory should not be a problem. The software is LR CC 2015.8. Can anyone advise what the problem is/

When LR creates a pano preview and displays that window, then there should be nothing wrong with your files or images as far as overlapping is concerned. If something does not fit with the images, it complains before even creating the preview, that is my experience.
I just did a pano with seven 22 MP Raws yesterday on my 8 year old MacBook with 8 GB of RAM, absolutely no problem, just takes a little bit longer. I am on OSX Capitan with LR 6.7, haven't updated to 6.8 yet, because so many people seem to have issues yet again with 6.8, mostly people on Windows from what I read in the posts.

If you are on Windows, then I guess, that it might have to do with that.

Michael, if you attempt the pano stitch with fewer than 8 files, does it work?

Hi Riki, I tried to do 4 photos at a time and they both worked. I then tried 5 and the program crashed. I also tried the 8 photos in ACR and that also crashed. Cannot work out why. Using Windows 10 machine. Kind regards, Michael

My first reaction is that we are hitting a hardware error. Have you performed any tests of the memory to ensure you don't have a hardware issue?

Hi Rikk, I have completed a memory test on my machine and all appears well. I took the 8 photos and attempted to create a panorama on another identical computer (Windows 10 and 32 Gb RAM). The same problem arose. The preview worked fine however, when I started the merge (and it got a little over half way) a message appeared saying Adobe Lightroom has stopped working. Windows has detected a problem and the program will have to be shut down. In fact on the last two occasions I have attempted the merge the program crash has actuallky crashed my computer. I am wondering if it has something to do with cache or temporary file storage or similar. When I did 2 merges each of four photos, I found it interesting that one of the merged files was 169 Mb whilst the second was 311 Mb this seems overly large given the starting raw file size. This problem is becoming most frustrating and any advice would be most welcome.  For your information I downloaded a trial version of PTGui to see whether it would do the job. I was able to import all 8 Raw files, create a preview and create the panorama; all in very quick time. A PSB file of 133 Mb was the final panorama. I now believe it is not a problem with the machine but a problem with the Lightroom program installed on it. Your thoughts would be much appreciated.

The next test to try, based upon what you've told me here, is to disable Rapid Start Tech and make the attempt again with Lightroom. That should tell us something about how they interact.  Have you tried this yet?

Hi Rikk,

I have been away from my computer for the last 24 hours and have not had a chance to follow the next step. I will have to do some research on how to disable/turn off the Rapid Start Tech. I am not sure how easy or difficult this is and what, if any, impact it will have on computer operation. I will hopefully have some further information tomorrow.

Kind regards,

Michael

Hi Rikk,

I disabled the rapid start tech and this made no difference in attempting to create the panorama. Lightroom still crashed. I am unclear as to the difference between Rapid Start Tech and Rapid Storage Tech manufactured by Intel. I have spent the day searching the Web for further information and I am still as confused as when I started and, of course, I still have no answer to my problem. Most frustrating!!! Any further ideas would be greatly appreciated.

Michael. Is it only this single set of 8 photos that is causing the crash - or does it happen on all panorama stitches of >4 photos?

Hi Rikk,

Funny you should ask this. I ran the same set of photos on a desktop computer that does not run all the Intel Rapid start/storage tech. and the same crash happened. This indicated to me that it might not be the computer or the software. I took another set of 8 photos (taken 5 min before the set I have been having problems with) and attempted to create a panorama. Amazingly all worked well. There must be something wrong with one or some of the photos in the original set; although I cannot think what the problem is as the preview works fine. IT is only when I attempt to create the panorama things go wrong. Now that I have got to this point, I am going to take a couple of different sets tomorrow to see whether they also create without problem. It looks like we might be getting close to s solution!!! Hope all goes well tomorrow. Will let you know. I will now have to work out what is wrong with the original photo set.

If you are having this issue on a Windows PC, check your page file settings.

I recently moved my page file to a 16 GB SSD I noticed was installed in an M-SATA slot in my laptop. I allowed windows to manage the page file but today after more investigation on this topic noticed it never grew to above 2GB even with massive amounts of hard page faults. (Windows 10, i7 CPU with 12 GB RAM installed and main drive is also SSD). Once I manually set the min and max to 10240 MB on the new page file I have been able to create Panos with 8 and 10 x 24MB Raw files which i have been struggling with for weeks. There are plenty of different opinions on page file settings but i think the issue here is that the page file on the M-SATA responds quickest so gets used which is how windows selects the page file to use in a multiple page file scenario (emphases on "Think")? bottom line, in my case, allowing windows to manage it simply didn't work for me and a little fiddling in this area has solved to me what has become an utter annoyance.

This may not be your solution but i hope it helps someone.
