Hi Erik, 'compression: lzw' sounds like this might be a tiff file with a jpg filename extension. I hope you still have the file so we can investigate.
This doesn't explain why it crashed the machine though. The only way this can happen is if the process uses too many resources, and some management system rebooted the machine to recover. Resources being memory, CPU, disk space etc.. Is the nona process being run by the web-server user as part of a web POST? This could easily bring down Apache (or whichever httpd server you are using). You might be able to reduce the resources available to each process/thread, this would at least keep the server running for other users. An alternative design would have a separate daemon process that picked up the image files one at a time and executed nona outside of the httpd software altogether. But your comment about .bashrc suggests that you are running this conversion process manually, are you connecting via SSH and running a script? Without root access you are limited to copying files and libraries, pretty much as you have been doing :( You could use PTmender instead of Nona, the scripting would be the same, but PTmender has fewer dependencies. -- Bruno On 19 October 2020 22:42:40 BST, Erik Krause wrote: >Hello, > >I use nona to extract cubefaces, thumbnails and preview images from >equirectangular source images on the WWP server (Ubuntu 14.04.5 LTS). >This used to work very well until recently, when I encountered a >special >jpeg file.
