Am I confusing this with multiple CA Gateways on one Linux box? Stupid
me. But it would be nice, wouldn't it?!
Dammit. I have to think...
Well ... actually we're using multiple VMware virtual machines (probably
linked clones), which have one IP address each and run one softIOC each.
That's the layer in-between that I was missing.
I'm sorry.

I still prefer having different IP addresses for different IOCs on

soft IOCs has to be rebooted.
How do you get the IOC (which still uses the old RSRV server, not CAS)
to bind to only one particular IP address?
RSRV doesn't make use of the EPICS_CAS_INTF_ADDR_LIST variable for
anything other than its CA beacon addresses, it still listens for
client connections on all interfaces it can find. If those interfaces
are on different subnets then this won't generally be a problem
(except for client programs that are running on that same machine),
but for two IPs on the same subnet this ought to give "duplicate PV"
errors to all clients that try to connect to that IOC.
Am I missing something?
