[PlanetCCRMA] Ardour files size limit?!?

[Robert Jonkman]

I'm having a problem with ardour.  For some reason, it always crashes
after recording for 15 minutes.  I thought maybe it was a screen saver
issue, but that doesn't seem to be the case.  Does Ardour have a file
size limit?  Is there anyway around this?  I want to use it to record
live performances.  The files are 320.8 megs in size with Ardour
crashes.
