Hi Coles,

The symptoms you describe occur when you try to run EPICS R3.13 with the
SENS IP kernel which is option with vxWorks 5.3 and I suspect mandatory 
with vxWorks 5.4. You can avoid this problem by choosing to _not_ install
SENs when you install vxWorks 5.3. The API used to query the broadcast
addresses used for each network interface card changes when using the
SENS IP kernel, and this causes original versions of CA to fail miserably.
I have installed a workaround for this problem into 3.14 and could back
patch 3.13 if there is a strong desire to use SENS with R3.13.
