Thanks Ralph,

And here some more useless information...
- Rebooted the Mac
- Found the IOC on a linux machine,
  being once started in the background as part of an automated test.
Most probably we have settings like this:
EPICS_CA_ADDR_LIST=127.0.0.1
EPICS_CA_AUTO_ADDR_LIST=NO
export EPICS_CA_ADDR_LIST EPICS_CA_AUTO_ADDR_LIST
Then we have a shell script to start the IOC, running
Base R7.0.4.1

The Linux box is connected to WLAN.

On the (rebooted) Mac (WLAN as well) the following
happens:

EPICS Base 7.0.3 (on the Mac):
  caget finds the PV sometimes, roughly 2-3 times of 10 tries
  cainfo does not find it.
EPICS Base  R3.15.5:
  caget fails always, and so does cainfo


I don't know if we should put more time on this issue ?
