JACK has either been shutdown or it
disconnected Ardour because Ardour
was not fast enough. Try to restart
JACK, reconnect and save the session.
It got the point where I couldn't work on the project anymore. I could open the project and playback my song, but as soon as I stopped playback that message would pop up and JACK would get Xruns. My session isn't extroidinary, it has 7 drum tracks that I recorded from Hydrogen, 2 guitar tracks and a bus. It has 7 effects running which doesn't seem like a lot since I have run more effects in Abelton Live and Adobe Audition before.
I investigated and tried to make sure my system was tweaked correctly. I am running Ubuntu Studio Hardy with real time kernel 2.26.24. I have my audio group setup in the limits file with unlimited memlock. My system has a 1.8GHz Core Duo and 2GB of ram. I don't have any hefty daemons/processes running. I am using a Edirol UA-4fx USB audio interface. I have jack setup with 128 frames and 3 periods. I got the same results when I turned the frames up to 1024. Ardour plays/records fine in a new session with just a few tracks. Other audio apps work fine with Jack. I built .116 jack and 2.7 Ardour from source with optimize flags and still get the same result. My hard drive is running in udma6 mode and gets 900MB/sec cached read and 40MB/sec buffered disk read. I have run the realTimeConfigQuickScan.pl from http://wiki.linuxmusicians.com and all checks are good. I am out of ideas and just want to make music, any help is greatly appreciated.
Thanks.
