If EPICS_CA_AUTO_ADDR_LIST is set to YES (the default) then the beacon address list is auto-configured using each of the network interfaces present on the local host. When fetching EPICS_CA_AUTO_ADDR_LIST, if envGetConfigParam returns a nill pointer, the server will decide to auto configure the beacon address list. So perhaps there is a 2nd possibility which might be that the system in question doesn’t have any operable network interfaces installed?
