[ardour-dev] Bug in 2.0beta9: unrequested looping, then hang

[Artem Vakhitov]

Hi,

I've been able to reproducibly hang Ardour 2.0beta9 with Jack 0.101.1 on Ubuntu Edgy in the following way:

1. Start a new session.
2. Set Jack as time master.
3. Set the playhead near the end marker of the session (say, one measure before).
4. Start playback.
5. Having reaching the end, the playhead returns to the place where it was set, and playback starts again (with no looping enabled!). This repeats several times, the the playhead goes beyond the end marker and stops shortly after. Transport controls start to blink randomly, Ardour hangs, CPU usage goes to 100%. In the console I see the line "no space in ardour-UI request buffer for thread disk butler" repeated endlessly.

I will gladly provide additional info if needed.

Cheers,
Artem Vakhitov
