Summary0008816: regular random segmentation faults
DescriptionI use ardour to record and listen back to my drum practice, recording a mix of midi and audio.

I often experience crashes when using this setup, usually during recording but sometimes during playback and occasionally when the program is sitting doing nothing. The crashes cause a loud noise through the audio output of the computer which can last from a fraction of a second up to a few seconds, which then stops when the ardour gui disappears. There are always a number of xruns that occur at the same time.
Additional InformationWhen the crashes happen, I am not interacting with the program with the keyboard or mouse.

I first started noticing this happen when I moved from ardour 5.12 (from the kxstudio repos) to the 6.X line. The crashes were not happening with 5.12.

I am using jack as the backend, because the midi is triggering a virtual instrument vst being hosted by Carla.

I have uploaded a backtrace from when this last happened. There were no plugins loaded in this ardour session.
TagsNo tags attached.

I don't know if this gives any more information than the backtrace already has, but when I was running ardour from the command line I'd get the following type of message right before the segmentation fault:

Zero fill end of peaks (@ 1235 with 62)

Are you using pipewire + JACK? or jackd?

It could be an issue in ARDOUR::PortManager::run_input_meters(), when Ardour accesses direct port-buffers (Thread 22, Thread 23),
Then again Thread 1 (GUI) is also a contender.

in gdb, there should be a message which thread crashed before the backtrace, that information would be useful.

I'm using jackd.

Apologies for not including that extra line. I've added a couple of backtraces from crashes I've had today.

Whoops, I pressed "add note" instead of "click here to upload".

All of the crashes reference ARDOUR::PortManager::run_input_meters()

Also, these crashes seem just as likely when the program is sitting idle as when I'm actively recording.

I tried creating a new session from the empty template, and then just left that sitting. It lasted over an hour without crashing. When I added a midi track and 2 channel audio track, ardour then crashed within about 10min. I'm going to do a bit more experimenting with this.

I did a bit of experimenting.
With just a midi track added to the session and connected to the midi input on my interface it lasted an hour with no crash.
With just a stereo audio track added to the session and connected to the inputs on my interface it lasted an hour with no crash.
With both midi and stereo audio track added to the session it crashed almost straight away, and a second time after a few min.

So it seems that the combination of a midi track and an audio track is causing me problems. I had record enabled on the respective tracks throughout this testing.

Can you try without JACK (use Ardour/ALSA directly).

If that does not crash, also a more recent version of jack -- at least 1.9.17, ideally 1.9.19 will likely solve this.

Thanks for the suggestions.

I tried without jack. It ran for over an hour without crashing, so seems likely that it is all good in that configuration.

I updated jack to 1.9.19, but unfortunately I'm still getting the same crashes.

I think I might have sorted out the problem.

I was connecting the midi_in to a midi input which was labelled as "UMC404HD 192k" in ardour. If I switch to the other midi input available, called "a2j:UMC404HD 192k [...] MIDI 1" then I don't get the crashes. These inputs are called "midi_capture_2" and "UMC404HD 192k [...] MIDI 1" respectively in carla (see attached screenshots).

I don't understand what the difference is between these two inputs, or why I am presented with two different options for the same physical connection.

I'll do a bit more testing to make sure this isn't a coincidence, but if successful I'll close this ticket.

Thanks for your help, Robin.

Aha. They should all be connected to "physical_midi_input_monitor_enable" (or at least some Ardour port). -- just like all hardware audio inputs are connected to the corresponding audio port.

Historically jack2's MIDI capture was unreliable (jitter, long delay), so the recommendation is to disable jack's built-in MIDI ports and rather use a2j.
See https://manual.ardour.org/setting-up-your-system/setting-up-midi/midi-on-linux/
With recent versions of JACK (IIRC >= 1.9.18) this i no longer the case and a2j is no longer required.

In some cases it can happen that MIDI ports were not connected to "physical_midi_input_monitor_enable".
This is now fixed since 7.0-pre0-1149-g437840dced -- please test.

Are you saying that having the "midi_capture_n" ports connected to "physical_midi_input_monitor_enable" should prevent these crashes?

I just tried that (see screenshot) and it still crashed on me. Could that be because a2j is still running at the same time? I am using jack 1.9.19 at this point.

I'll continue to use the a2j port for now.

The a2j ports also have to be connected. or just don't start a2j

Then there is also a problem that the ports have to be connected before ardour uses them.. so manual connection may be too late.
