Jeff, 

Recall that if this is 3.14.10 on a little-endian architecture (e.g. Intel) then there is a bug that causes this message:
>    "The CA server's beacon address list was empty after initialization?"

if EPICS_CA_AUTO_ADDR_LIST=NO

Andrew,

I sent this message to tech-talk ([email protected]) some time back but maybe it didn't go through. I am suspicious because I sent another one later and it did go through (so this isn't maybe a delay related issue).

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?
