Hi,
   This is nothing particularily new. I'm just presenting it to
represent what I'm seeign and get some guidance about how to find out
what's going on.

   This is my AMD64 machine. It was VERY lightly loaded. Just Gnome
and Aqualung which was running using Jack. Around 1PM I went to the
other room to watch a DVD and returned around 3PM. The only thing I
can think of that would cause an xrun around 1:23 or 1:34 would be
xscreensaver, or possibly soem updatedb operation that might have
started.

   When I returned at 3PM I started copying some audio files across
the network to a ogg file server. This was about 400MB of data. The
copies worked fine but during the copies I got a few more xruns:

12:08:46.070 Audio connection change.
12:08:48.119 Audio connection graph change.
subgraph starting at qjackctl-8905 timed out (subgraph_wait_fd=17,
status = 0, state = Finished)
12:10:27.191 XRUN callback (1).
**** alsa_pcm: xrun of at least 3.553 msecs
13:23:38.218 XRUN callback (2).
**** alsa_pcm: xrun of at least 2.263 msecs

**** alsa_pcm: xrun of at least 0.462 msecs
16:05:41.308 Audio connection graph change.
16:05:41.430 Audio connection graph change.

After the copies stopped the machine was idle until I wrote this
email. I'm also running MythTV on here right now. No problems.

Just a few xruns I'd like to better understand and get rid of over time.
