Try rebuilding your vxWorks kernel to include support for the SNTP
protocol. As I recall, this is under network/protocols in
the Tornado II configuration tree.

Its difficult to determine more about the cause of this w/o a stack trace.
To get one use the "sp" command to run ca_test and then type "tt <task id>"
for the suspended thread. My initial guess is that some vxWorks specific
libCom initialization isnt getting executed prior to ca's initializing
itself.

The message on vxWorks about "no compiler support for C++ exceptions"
in the first release of EPICS R3.14 results form a configuration
mistake. There _is_ support for C++ exceptions in vxWorks 5.4.
This is fixed in the next release of R3.14.

Yes, if your server is on one of the subnets attached to your IOC.

These steps are required only if you do not wish to run CA on its default
port number. If so, make certain that the server has identical configuration
for the EPICS_CA_SERVER_PORT.
