Kevin,

Your Solaris-8 IOC (acting as a client) probably does not see the server's
beacons because they are addressed to subnet on which your client IOC is not
listening. The EPICS R3.14 CA reference manual explains this situation in
more detail than in past versions of the manual. See the section entitled
"Dynamic Changes in the CA Client Library Search Interval".

It may be that a simple solution will be to expand the server's beacon
address list so that beacons are broadcasted also on your Solaris-8 IOC's
subnet. Alternatively, you could install a CA gateway providing transparent
connectivity for remote clients.
