| Summary | 0008452: Ardour 6.3 crashes seconds after loading moderately sized session post-reboot | ||||
| Description | I worked without issue on a session, sixteen tracks and a handful of built-in plugins. After a reboot I am having an issue with this session crashing every time I load, roughly 5-10 seconds after loading. Playback works, editing works, until the crash. | ||||

This does not happen when starting a new session, as far as I can tell. |
|
|
The gdb backtrace is sadly not useful (you need a debug build e.g. from https://nightly.ardour.org). When opening the session, does using "Safe mode: disable plugins" (checkbox in recent session dialog) help? |
|
|
Disabling plugins with safe mode does not resolve the issue. For reference, there are 3564 resources defined on the (default) right-side panel.

!!! ERROR !!! - Insufficient disk space in /tmp/selfgz1712921 /dev/mapper/kfbook--vg-tmp 1.8G 5.7M 1.7G 1% /tmp The install unzips itself to /tmp first, you can try chmod +x Ardour-6.3.246-dbg-x86_64-gcc5.run TMPDIR=$HOME ./Ardour-6.3.246-dbg-x86_64-gcc5.run or install it manually in steps, see `./Ardour-6.3.246-dbg-x86_64-gcc5.run --help` |

> For reference, there are 3564 resources defined on the (default) right-side panel. That is a lot, but not usually an issue of concern. Another guess: Ardour runs out of Memory. Perhaps caching waveforms for all those regions (which are rendered in the background). does `dmesg` show some "OOM" message? |

Thank you for the assist here. I was able to install the debug version 6.3.246-dbg-x86_64-gcc5 I'm using ALSA in lieu of JACK, which hasn't been an issue in the past. Not sure of the details regarding memory and if it could be causing the issue I'm seeing. Opening and playing the session is now working, without crashing, but the audio is overloading and the DSP indicator is between 95%-100% where it usually is 0000023:0000020% average. This only happens when plugins are *enabled,* playback and editing seem to work fine without crashing on the debug build w/ safe mode enabled. To summarize: Release Build: Without Safe mode, nominal DSP, overflows detected and aborts. With Safe mode, nominal DSP, overflows detected and aborts. Debug Build: Without safe mode, extreme DSP, overflows ignored (?), playback continues without abort but is choppy. With safe mode, nominal DSP, playback continues, no aborts. Here's a gist including the output of a few configuration files, the "Help -> About -> Config" output, as well as the Ardour stdout output for both debug and release executions. No core file to be had, yet, until I can reproduce a crash w/ the debug g https://gist.github.com/kfrz/648cb12daf47d42ff471dbe277612179 |

Whoops, didn't realize my syntax error in the last note, "0000023:0000020% average." should read " about 20% average" |
|
|
No "oom" in `dmesg`, nor anything else of note. |

Does an optimized nightly build 6.3-250 also crash? Debug builds need more DSP (sometimes twice that of an optimized version). What buffersize / sample-rate are you using (Menu > Window > Audio/MIDI Setup) Also Ardour/ALSA (and other built-in backends) report worst-case DSP load, while JACK averages it (I've seen cases where jack reported 30% on average, but there were x-runs -- occasionally spikes 100% load, but still low average). |

Good news (I hope) - the optimized nightly build seems to work fine, without any crashing (yet). |
