Summary0002709: Ardour crashes very often while zooming
DescriptionHello!

I'd like to report an issue which I have experienced in all versions of
Arodur (since 2.2 or something). At the moment I use 2.8.
My hardware/OS are: Edirol FA-66, AMD x64 6400+, 4 GB RAM, motherboard Asus
M2N32WS Pro, nVidia gr. card; 64studio upgraded to Debian (unstable),
realtime patched kernel 2.6.26.8-rt16 (a few weeks ago I used
2.6.24.7-rt17, and several months ago had used a different Debian distribution - no difference, the issue has remained all the time), self compiled Ardour
(some months ago I had used distribution provided Ardour, but there was no
difference too)

And the only problem I have encountered so far is frequent crashing while
trying to zoom in (haven't noticed any crash while zooming out). And no
matter if I use the 'Z' shortcut, and try to zoom with my mouse or just
click the '+' button to zoom, Ardour will crash eventually (more less once
per ten zooms).
Yesterday I had a two hour Ardour session where I needed to 'concatenate'
several audio regions (move them, and zoom in to attach them as close as
possible to each other), and I had about 10 crashes which was really
annoying.

I am willing to donate some noticeable amount of bucks especially for this purpose (or just support Ardour generally) if that could help developers to pay closer attention to that problem. Ardour is extraordinary software, and I want to use it with my home recordings, but would like to have the environment stable.

Below I am attaching the bug report Ardour generated yesterday. If it's not
enough, please let me know what I should do to provide you with more
details about the problem.

Thank you very much for you great work & software!
B. Regards,
Tomasz Grzelak
Steps To ReproduceIt happens randomly, but usually Ardour crashes once per ten times when I want to zoom in.
Additional InformationAttached the bug report generated by Ardour.

 Yes. Ardour 2.8 crashes randomly while zooming out (!) here. I do it via CTRL-scrollmouse.

-> segmentation fault (in the console)

Ardour just disappears.
Appears ca. every 10 minutes while working (and recording with people...)

linux 2.6.30 (appeared also with 2.6.29 and 2.6.28), fluxbox, debian testing, self-compiled Ardour 2.8, 2 monitor setup (randr), AMD quadcore 64bit.

!Please update to priority high!

For me it crashes while zooming in... Haven't noticed a crash while zooming out.

Any way, how can I update the priority to high? I cannot see an option to edit my request or just change its prio level.

This was confirmed by Ben on IRC at one point, we are looking into it but it is difficult to track down. We really could use some backtraces that are from Ardour when built with DEBUG=1 as described in the debugging ardour page on the website. Thanks.

Sorry for late response.
I'll try to recompile ardour with debug enabled, and attach a trace this weekend.

OK, I've checked it but now I'm totally confused...
I downloaded and compiled Ardour 2.8.1, and did not have a single crash during a few tens of zooms in & out!
What's more interesting, next I run ardour 2.8 (which had crashed so many times during my last project it had inspired me to log the bug), and I didn't have any crash in there neither! So now I'm wondering what the hell happened...?????

During last few weeks I changed my hardware (switched from AMD to Intel; replaced motherboard, CPU, RAM and a graphics card), but the system and software are almost the same - I have not touched any single component of the system besides kernel (I compiled it with the same config but with support for Intel and my new chipset), I even used the same jack/ffado + hydrogen + ardour compiled on my old AMD.

Could the issue be somehow hardware related? Or AMD related??? I really don't know what to think about this now...

I'm preparing for recording another composition soon, so it will give me deeper possibilities for testing, and confirming the situation, but at the moment the bug seems to have disappeared magically :/

can the other reporters still reproduce this issue with 2.8.2 or current svn?
i doubt that it's hardware-related, but maybe the issue got fixed in passing...

nettings it is still an issue. It is a aknown bug and I believe a priority to knock out before 2.8.3 It is just very tough to track down.

Yes, here too. It is very hard to reproduce though.
I'm currently editing some drums very heavily and Ardour crashes pretty often.
What I do:

Zoom in, cut a region on two locations, move the region, set the playhead in front of the new crossfades, playback, zoom out, listen again to that piece, maybe have a look at it again with some zooming, then zoom in to the next beat and repeat the whole thing.
This happens very quickly, and after some minutes or sometimes quarter to half an hour of work, Ardour crashes when I want to zoom out (CTRL-Mousewheel).

Hello,

finally, some fresh info regarding the problem.
Several days ago I managed to upgrade to Ardour 2.8.2, and spend some time with recording.

The first warning I got when starting Ardour was this:
---
WARNING: Your system has a limit for maximum amount of locked memory!
         This might cause Ardour to run out of memory before your system runs
         out of memory. You can view the memory limit with 'ulimit -l', and it
         is normally controlled by /etc/security/limits.conf
---
ulimit -l gives me 3072000

I'm not sure if this is related to those crashes...
But any way, now I think I know how to reproduce the problem (at least in my environment).

First I'll describe when the problem does not happen - e.g. I open an already saved session, and I can zoom in and out without crashes. At least during tens of zooms I had no crash.

And now, crashes happen when I work with Ardour for a longer time, and make some (many) recordings. After that, when I want to zoom particular regions to move them as close as possible to each other,
Ardour crashes quite frequently.
I've attached files with debug messages from two different crashes (ardour-2.8.2-bugreport.txt and ardour-2.8.2-bugreport_2.txt). I hope they will help to find out what's wrong.
And if there's anything more I could test from my side, just let me know...

Hello,

a question rather to developers - any news in the topic?
Is the issue being researched?
I'm willing to help and provide more info or test results if needed.

B. Regards!

I haven't been paying attention to Ardour developments in a while but after just testing the most recent 2.x version (2.8.12), I realized that this bug is still present. Any updates on a possible fix happening?

Are these crashes, or does Ardour hang up?

Straight crashes, Ardour just exits.

Does anyone have a relatively small session which allows this bug to be reproduced reasonably often?

Because of no response to this case for very long time, I decided to buy Mixbus. Although it is based on Ardour, it does not seem to be affected by the problem. I've been working quite heavily on a new song for a few weeks already, and didn't get the crash even once.
I wonder whether the issue may be related to some system libs and compiling Ardour from source? Although I had used a few different OSes (64studio, Ubuntu Studio in different versions) I had always compiled Ardour from source, and encountered the problem. Mixbus is obviously a binary, and seems to run stable in my environment.

I've used both binary packages and self-compiled source, and always had this problem. In a typical (large) session where I'm comping tracks (so lots of editing and zooming), I get crashes literally every two minutes. It seems that crashes are much less frequent when I do fewer editing operations, though.
Interesting that Mixbus doesn't seem to be affected. Maybe I'll try it some time...

You should clarify what you mean by binary packages? Do you mean the self-contained binary that can be downloaded from ardour.org? Or do you mean binaries from your distribution.

Mixbus is pretty well identical to Ardour in this regards for the record, there isn't any code I know of that would fix this in Mixbus but not Ardour.

I've been using my distribution's (Ubuntu Studio 10.04) binary, Ardour 2.8.6 (revision 6550), for the longest time but have downloaded a self-contained binary of 2.8.12 from ardour.org a few days ago. I'm not noticing any differences in crash frequency between the two so far.

 Is this still going on? I couldn't reproduce this on my Gentoo Linux (will keep trying), but I find this part of the backtrace interesting:

0000004 <signal handler called>
0000005 0x00007f7cabe2b30a in pthread_mutex_lock () from /lib/libpthread.so.0
#6 0x00007f7cadf7d4d7 in Glib::Mutex::lock (this=0x3785978)

    method=0x8db562 <AutomationLine::reset_callback(ARDOUR::AutomationList const&)>) at libs/ardour/ardour/automation_event
.h:165

My ardour 2.8.13 (built from revision 12983) (2.0-ongoing) has this in libs/ardour/ardour/automation_event.h (line 218):

mutable Glib::Mutex lock;

and at line 162 there's this:

template<class T> void apply_to_points (T& obj, void (T::*method)(const AutomationList&)) {
    Glib::Mutex::Lock lm (lock);
    (obj.*method)(*this);
}

Now, the note here:

http://developer.gnome.org/glibmm/unstable/classGlib_1_1Mutex.html

says "Glib::Mutex is not recursive, i.e. a thread will deadlock, if it already has locked the mutex while calling lock(). Use Glib::RecMutex instead, if you need recursive mutexes."

It's theoretically possible that a new zoom request comes in while this one got past the Glib::Mutex::Lock constructor, but not yet past it's destructor, and locks the mutex again (presumably somehow asychronously but in the same thread? - a case covered by a RecMutex).

Since I couldn't reproduce the issue with my build, if somebody else can, could you replace "Mutex" with "RecMutex" in the "mutable Glib::Mutex lock;" line and see if the problem persists (and generally see where the application is better served by recursive mutexes)?

"If the mutex type is PTHREAD_MUTEX_DEFAULT, attempting to recursively lock the mutex results in undefined behaviour. Attempting to unlock the mutex if it was not locked by the calling thread results in undefined behaviour. Attempting to unlock the mutex if it is not locked results in undefined behaviour."
