Ardour crashing with error about not being fast enough.

I have a project that I was working on in 2.3 and I started getting this
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.
