I added EPICSlinux to the hosts file as just a local host. I am still getting the same issue. In the address list all I have in there right now is 127.0.0.1. Thanks for the help.

Hi:
You have an <west coast>interesting</west coast> computer network setup ;-)
The root of your problem seems to be this:
com.cosylab.epics.caj.impl.ConnectionException: Failed to connect to
'/127.0.0.1:5064'.
at com.cosylab.epics.caj.impl.CAConnector.connect(CAConnector.java:138)
...
Caused by: java.net.UnknownHostException: EPICSlinux: EPICSlinux
at java.net.InetAddress.getLocalHost(InetAddress.java:1354)
I don't know exactly why the CAJ library wants to resolve a host name in
that context.
Do you explicitly use "EPICSlinux" in your address list?
In the past, there have been similar issues because just so that it would
later be able to present you with nice looking error messages,
the CA client library tried to resolve host names. Maybe that's related?
In any case, it might help to define EPICSlinux as a host in /etc/hosts so
that the name resolution 'works'.
