Classic? Superserver?

If it was OK before and now is not, then something changed. Windows
auto updates? Faulty RAM? An anti-virus program that's hitting the
database file?

-- Anything interesting in the firebird.log preceding the crash?
-- Are you using Classic or Superserver? (or maybe Embedded?)
-- How many connections are being made by the middleware?
-- What connection protocol is the middleware using? (TCP/IP? Named
Pipes? local?)
-- Are multiple connections threading across a local connection?

etc.
