Andrew/Jeff
Thanks for the patch suggestions. Turns out the problem was PyEpics 3.0.11 on 64 bit systems. Matt had already fixed it with the latest version that was in the repository.
I certainly appreciate the help.

Hi Mark,
Please try applying the patch from the 3.14.12 Known Problems page dated
2011-02-16 to your EPICS Base installation to see if it helps. This patch has
been reported to fix a couple of CA client issues at different sites now, and
if it helps you too I'll make it more prominent on that page.

An error is only a mistake if you don't learn from it.
When you learn something from it, it becomes a lesson.
