Have you eliminated the possibility that something else is competing
for the server's service port? (default port 3050). Get suspicious
if there are multiple versions of Firebird (or Firebird + InterBase)

about, ask the site Admin who is connecting to that machine late on
Sunday night and to what it is expected to connect....
