[ERROR]: Could not understand ardour file... Session fails to load... XML issue...

After working several hours on a piece for a portfolio, several tracks disappeared after undoing several steps. This prompted me to restart ardour through the shortcut Ctrl-Q. When I tried to reopen the file I received the following messages in the log…

[ERROR]: Could not understand ardour file /home/maxwell/texture/texture.ardour [ERROR]: Session "/home/maxwell/texture (snapshot texture)" did not load successfully

I tried again through the terminal and received the following in the terminal:

I renamed texture.ardour.bak as texture.ardour and tried to open that, but I received the same errors. I know that it must be an error in the XML file, but I am having a hard time figuring it out, here uploaded a link below of the the XML file.

Let’s see… I don’t know what else you need to know… I am running Ubuntu Gutsy, and I compiled ardour from source (2.1)… I am also running Jack 0.107.5, and I am using a Focusrite Saffire LE through Freebob… Ardour has been running pretty smoothly… every once in a while it shuts down, but nothing like this has happened before.

Thanks!

yeah… i noticed those files as well. i have them in my /interchange/…/audiofiles folder too. i think they came from when i previously tried to bounce the “beeps” track. when i attempt to delete them from the xml file, recieve the “programming error: unknown region type passed to Session::add_region()” error upon starting up ardour.

as for memlock… i have it set at 250000. i have commented it out of limits.conf in the past, but i still received the same error upon startup so i uncommented it. do i have to comment it out and recompile ardour for the error to go away?

You’ve got some extremely oddly names for audiofiles present in that session file. Do you have any idea where these might have come from? examples:

 name="@<ù¶@-574450.wav"
 name="beepsbeeps__-R@-578790.wav"
 name="Ïÿÿÿ@-578790.wav"
 name="beepsbeeps__-R@85630.wav"
 name="@85630.wav"
 name="beepsbeeps__-R@90990.wav"
 name="@90990.wav"
 name="beepsbeeps__-R@91440.wav"
 name="8\À¯@91440.wav"
 name="beepsbeeps__-@-102600.wav"
 name="8\À¯@-102600.wav"
 name="beepsbeeps__-@49310.wav"
 name="8\À¯@49310.wav"
 name="beepsbeeps__-R@73850.wav"
 name=" @73850.wav"
 name="beepsbeeps__-@52540.wav"
 name=" @73850@52540.wav"

ardour is also warning you about a limit on locked memory size that could have some relevance to this problem. what does your /etc/security/limits.conf say about your mlock limit?
