Thanks for the response Kai,

I'm not runnng any other jack software so I don't think this is an issue
with the jack Transport but I added your suggestion just to be safe.
I tested my example code an an older system I have access to and found that
it ran flawlessly. This older system is a Fedora Core 5 machine with the
following software versions:

kernel: 2.6.16-1.2080.16.rdt.rhfc5.ccrma

Can you or anyone make sense of this? This application runs great on Fedora
5 machine with older ecasound versions but will not run on an updated Fedora
8 machine for more than about 10 seconds before Ecasound stops. What might
be causing this?

Thank so much for taking time to read this and offering any ideas you may
