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.
