This is (not so) well known issue with Win9x/NT. AFAIR, it has something
to do with sequencing of IP packets, and at critical moment one packet
gets lower number than previous, so system concludes that connection is
dropped. Firebird is not the only application that can suffer from it.
AFAIK, the solution is to either use other OS, or to restart the
computer periodically (once per month should do it).
