The olbd doesn't (by default) run on port 1094. It is the xrootd that
(by default) would run on port 1094. Normally you would tell it which
port to use in the config file with the "olb.port" config directive.
Hmm, I just checked on that machine and the _xrootd_ is definitely
running on port 1094 and not port 34459, so something strange happened.
I'm in the process of screwing around with things on bbr-stk1, so
don't be surprised...
BTW, you can shut up this warning:

> service "rootd" with protocol "tcp"
by explicitly specifying port 1094 to connect to xrootd on the client
side. For BaBar this will mean changing:
read /store/* xrootd bbr-rdr.cr.cnaf.infn.it/
to
read /store/* xrootd bbr-rdr.cr.cnaf.infn.it:1094/
in your (BaBar) KanAccess.cfg file.
