   This message come from XNET listeners which can't create named object in
shared memory. You may ignore it if you don't use XNET at given Firebird
instance. Or, you may disable XNET: add switch -i to the command line of
firebird executable. Also, you may set IPCName setting in firebird.conf to
the different values at every firebird instance (client should have same
setting to be able to connect).
