Hellkeeper · March 13, 2018 at 9:29 AM

Hey there,

any ideas to this Error why I try to process a Pano?

Code

-bash-4.2$ /path/to/krpano/krpano-1.19-pr14/krpanotools makepano -config=/path/to/krpano/krpano-1.19-pr14/templates/mycustom.config  '/path/to/source/296.jpg'        
krpano makepano tool 1.19-pr14 - 64bit (build 2017-12-01)
- using config: mycustom.config
processing - 296
 - converting sphere to cube format...
Killed loading... 99%

thx, bye from Austria

Hi,

normally the tools should start swapping-out the memory when the OS doesn't provide any memory anymore...

When the OS is killing the tools but at the same time reporting enough free memory the system itself would act a bit strange...

Btw - which system?

You can try this calls and report the output:

Code

krpanotools transform -meminfo

and

Code

krpanotools transform -memtest

Best regards,
Klaus

Hey Klaus,

it's a "CentOS Linux release 7.4.1708 (Core)" Linux virtualized in Hyper-V 2012R2 with 9GB Memory provisioned.

I run the `krpanotools makepano` script on a VM in a cloud.

The command `./krpanotools transform -meminfo` gives this:

Code

totalmem:  1682 MB
availmem:  1057 MB

and `./krpanotools transform -memtest` this:

Hey philippeK,
not sure anymore as it's already a few years in the past ... but I think I just threw more memory on it ...
VM is running with 16GB currently ... so I guess that was the solution ... :)

Thank you Hellkeeper for such a super quick response .

But I've found another solution rather than adding more memory.

My VM didn't have any Swap file, so I think when krpanotools reached the limit of memory it tried to use a swape file, but none was available.

Here is the guide that helped me to resolve this issue: How To Resolve "Out of Memory" Errors on Ubuntu 17.10. It also worked for my VM (Ubuntu 20.04).
