OK. Guess I could've been more specific ;) I'm using 64-bit Arch Linux 0.8(Voodoo), with default package. All packages are the latest version available in repo. libsndfile is 1.0.17-1 JACK is 0.103.0-1 And one more thing. Ardour seems to bring JACK down with it upon crash. |
|
|
Something that might be of interest: Upon the crash, jackd says: jackd_client_create_thread: error 11 creating thread with default parameters: Resource temporarily unavailable could not start create freewheel thread Also, upon startup, ardour says it can't lock down memory for rt thread (can't allocate memory) |

Hi I think I'm experiencing a related issue here. I've uploaded my session file (joesitting.ardour). I'm running the current SVN version (which I update almost daily) on UbuntuStudio 7.04, i386, JACK 0.105.0 When I export the session, ardour creates the wav file filled with silence. Sometimes there is a loud crack / peaking sound immediately as it finishes the export. Sometimes it crashes at this point (leaving JACK running), but most of the time Ardour keeps running. No message are output to the console during or after the export, but I've included the console output below anyway. Interesting thing is that during playback everything seems fine, but during the export, the track level meters indicate sound on the wrong tracks and at levels much higher than during playback, and the master level meter indicates no sound at all (hence the silent wav file). This appears to be some kind of bug with the audio routing to the master track during export.

just a note: 2.1pre (trunk in svn) is known to be broken. you should expect to discover more issues like this for a while. |

Thanks Paul I've switch to the ardour2.0-ongoing branch - all is working well again. Thanks to all the Ardour developers for providing such an awesome DAW! |

I solved it. It had nothing to do with Ardour, but with jack. It appears that there's a bug in JACK on x86_64 that messes up memory locking. Disabling memory locking bypasses the export bug. It's not a beautiful solutio, though, and I will try to discuss it with the JACK developers. Thank you for your patience. |
|
|
most of us *are* the JACK developers. what do you think the bug is? |
|
|
It might be a configuration issue on my part, but I'm experiencing that JACK is unable to lock memory on linux kernel 2.6.20.7 SMP (x86_64). I'm getting "unable to lock down memory for RT thread" messages. Might be a kernel bug. I think something about SHM and/or IPC is faulty on x86_64 in this particular kernel release. I'll upgrade the kernel and see what happens. |

see notes. it would be nice if we didn't crash when this happens, but the problem seems barely understood. its certainly not an Ardour issue as far as i can tell. |
