Summary | 0009135: Ardour Session contains 140 MB of automation data and crashes | ||||
Description | i There, I used fader automation and the whole session is not working anymore, because it got really slow and crashes all the time. I first thought it is the same bug as @tired_eyes reported here https://tracker.ardour.org/view.php?id=9117 ("Automation: combining two [midi] regions create an excessive amount of automation points"). But i have the problem with audio regions and they are not combined. Just huge amount of automation data. When i load the Session, it takes about one minute which is very long in comparison to other projects i worked on. While loading i see all my 8 GB RAM filling up and also the Swap going up and my system is showing me the note, that ardour is not responding. Once i see the editor view, the session is behaving very slow and playback starts with a delay of about 5 seconds. Sometimes i got notified that my storage (SSD) isn’t quick enough for playing back simple Audio tracks (about 10 Tracks with Flac files). I realized, that the .ardour file is about 140MB huge. Once i deleted the Track with the Fader-Automation, the session is only 1MB. That means, there was is a ton of automation data in there. That surprises me, because the fader automation (that i recorded) is only for a region of about one minute. What i find strange, that in the session folder, there is no .history file, but a .history.bak file of 400MB (which you can see in the screenshot). That .history.bak file is from the point of the screenshot on only automation data. I never deleted my .history file (or can it go away with a new snapshot?) and i wonder where it’s gone. I can’t even show my fader automation data, because ardour is struggling to zoom in. Besides ot that: Thank you guys for the wonderful DAW that Ardour is. I’m using it for years now and never wanna change! | ||||

How did you create that automation-data? have you recorded this fader automation with a control surface? There was a bug in Ardour7: automation thinning did not work correctly. Usually Ardour removes dense automation points at the end of each write pass. Fixed now in 7.1-207. If that session is important to you, there are a few ways to recover it: Either just delete the Automation in the .ardour session file using a text editor. If it is fader automation, you can use a Lua script that comes with Ardour to remove dense events: Open Window > Scripting . Load script "Snippets > Thin Fader Automation", select the track(s) that have fader automation, press "Run" (in versions prior to 7.1-207. change line 30 from al:thin (50) to al:thin(128000). You can also safely remove the .history file (that is undo/redo data). |

Thanks for the response! I have recorded the fader automation just with ardour by hand with the write mode. Control surface? I didn’t use any extra software or hardware (fader) to do this. So nothing special. Thanks for the recovery tipps. Luckily i could restore from backup but good to know for the (hopefully not) next time. I’ll try to open my "corrupted" session with Ardour 7.2 when it’s out. In the moment i unfortunately don’t have time to learn how to use lua scripts or to install nightly builds of ardour. |
