Summary0000630: "Background rendering" makes the pc crash
DescriptionHello to all,

Having used the background rendering on a project of more than an hour I was surprised by the crash of my pc.
After rebooting and analysis I deduced the following:
- Having 126 Gb of ram memory I preferred to put the /tmp directory in ram rather than on the sd drive (ram being faster and thus I relieve my sd drive).
- When, in cinGG, you stop the rendering function in the background and then restart it, it does not delete the old /tmp/brender files. As a result, the ram memory keeps filling up and eventually crashes the PC.
- Because of the large number of /tmp/brender files created, it is impossible to delete them via the graphical file manager. The only possibility is to restart the pc to empty the /tmp directory.

In order to avoid a new crash or a reboot of the pc, the simplest solution I found is to add to CinGG this shell command that deletes all /tmp/brender files -> find /tmp/brender* -delete

Now, at any time, I just need to disable background rendering (MAG+G), run this shell command and then re-enable background rendering (MAG+G). If this is not clear, I can make you a video.

This is not the discovery of the year but I think it would be important to either:
- to add this shell command (or another one) directly into CinGG as I did.
- to mention it in the manual.

Of course, with my configuration, it's the memory that ends up saturated, but the result would be the same on a sd or dd drive.

Have a nice weekend.

Your recommended solution is in this month's AppImage release. As noted in the releasenotes.pdf, it will only show up for new usage of CinGG so as not to destroy any shell scripts a user may have added to his own usage (seen in $HOME/.bcast5/Cinelerra_rc). But you can test this if you download the latest AppImage without impacting your settings by typing in a terminal window:
    CIN_CONFIG=/tmp/bcast1 /location_of_your.AppImage
You will see when you click on the Shell Commands, a new one on the end "Delete brender files in tmp".

Good idea. I am working on adding a Shell script to do this.
