EDIT: Moved the trace into pre-formatted text for easier reading – Seablade
This is missing some critical information really. This should be repeated with a debug version of Ardour so that line numbers of the source appear in the trace, but also some info above the stack trace which identifies the crashed thread. Actually going off memory I had thought GDB also identified it in the thread which I don’t see, so this may not be of a crash?
Seablade
Seems to be the issue is here… does gdb print at the top that it’s “Thread 27” that crashed?
And yes, like @seablade mentioned line numbers and parameters are needed. It’s not obvious why this would crash. Maybe Ardour just runs thread while the issue is elsewhere.
Thread 26 is another contender:
Apologies, yes I somehow missed this output from GDB

() from /opt/Ardour-6.9.0/lib/libardour.so.3
Re repeating this with a debug version of Ardour, sorry, is that something I can do from within my current install or do I need to download something else? That debugging manual page only seems to reference GDB for linux systems.
Grab a debug version from here:
https://nightly.ardour.org/list.php
Make sure you grab a 6.9 version (Not 7.0-pre) and a free version would likely be fine for this purpose.
Seablade
By the way, you can make the output you are pasting from the terminal with GDB into preformatted text and easier to read by surrounding it by three backticks ```
This is on my US keyboard found on the key above the TAB key.
Seablade
Thanks everyone, here’s the gdb output running a debug version of 6.9, hopefully better formatted

Any chance you are changing scenes in OBS shortly before this crash?
This seems like the Jack Port is being deleted without telling Ardour somehow at a first glance, but Robin may have some better thoughts.

Hi Seablade
No action taken in either Ardour or OBS by me, I have OBS open, I open Ardour, open an existing session, leave it a few minutes and it crashes. I’m assuming it’s something to do with the Jack input client in OBS because the same Ardour session doesn’t crash with OBS not running, but I’m not sure what that issue is as I’ve done it before with earlier versions of both OBS and Ardour and it’s worked fine. I’ve tried various configs in the audio routing grid to get the audio to OBS but whatever config I use that results in audio actually reaching OBS it crashes Ardour shortly after.
Thanks
Bransby
This is helpful. The problem is reading data from MIDI hardware devices to keep track of their activity. I do however have no explanation why this can fail in this way.
Which version of JACK are you using (jackd --version
), and how have you configured JACK MIDI (-X seq
, or a2jmidid
)?
Do you have a MIDI keyboard or some sound-card with MIDI I/O that can be disconnected?
Hi Robin
jackdmp version 1.9.12 with a2jmididi
I have an m-audio midi controller keyboard connected to a Behringer UMC404HD via midi cable. The UMC404 is USB and has midi I/O although the Ardour session in question isn’t using any midi tracks.
Thanks
Bransby
It’s not about MIDI tracks, Ardour monitors input of all hardware devices (check Menu > Window > Recorder).
Can you check if the issue persists if you don’t run a2jmidid
?
Interesting, so I’ve turned off a2jmidid, started the session and everything seems to be running fine, it hasn’t crashed after about 10 minutes, however, in the audio routing grid I can’t connect anything to the jack input client for OBS.
I restarted, turned off a2jmidid, started ardour, then started obs and can now connect audio from Ardour to OBS with no crashes.
So now how do I use my midi controller keyboard in Ardour without a2jmidid running? And why is a2jmidid the problem? I have definitely run this same configuration of audio from Ardour to OBS in earlier versions without disabling a2jmidid
The problem seems to be due to a new feature in Ardour 6.7: MIDI input meters.
One workaround is likely to use JACK’s built-in MIDI support instead of aj2.
With jack1, and recent versions of jack2, a2j should not be needed anymore.
Thanks Robin, I hadn’t realised that about Jack’s midi support, when I first setup my keyboard I couldn’t get it working without a2j, although to be fair that was quite a while ago. I’ve now turned off a2j and using seq the midi keyboard and inputs are working fine and I can pass audio to OBS without any crashes.
Thanks for all your help.
