Ardour crashes when i stop recording

Ardour (running on ubuntu) sometimes crashes when i stop the recording with space bar. Crashes in Jack and Alsa.

On jack i get the error: terminate called after throwing an instance of ‘Jack::Jack Temporary Exception’ what():

And on alsa: Speicherzugriffsfehler (Speicherabzug geschrieben)
watched PID no longer exists - releasing device.

Has someone other this problem? I think, in the version 6.5 i didn’t have this problem…

Works fine here, but it could be something specific to your system, or plugin(s), or perhaps it depends on some setting.

Can you get a backtrace, see Debugging Ardour:

Ideally run a recent version debug version from e.g.

/opt/Ardour-6.6.455/bin/ardour6 --gdb

and report the issue at

Thanks Robin. I tried now different times with the bugtracker but now works and didn’t crashes. It is difficult when it only crashes sometimes. But I stay on it and maybe I manage to make a backtrace.
