It appears that your CA repeater is running and that it is
listening on port 5065. Perhaps the CA client was not started
with EPICS_CA_REPEATER_PORT set to 5065, but I think I recall
correctly that this was not your situation?

Is your MEDM compiled and linked with this 2003-03-12 base
snapshot? Do you see this problem when the "caEventRate <PV
name>" is run from the 2003-03-12 base snapshot?
