This is not about kinterbasdb, as the error reported comes from Firebird
client library, and it clearly said that the connection was rejected by
remote host. There is no way how this error can come from kinterbasdb.
So I would look for the cause at network interface level or process
spawning. The problem is either in OS or Firebird itself. Guess it's
better to ask in Firebird-Support list.
