What do you see in the firebird.log prior to the Guardian restarting?

However, don't eliminate the possibility that you are getting some periodic
fatal error occurring due to your use of the BDE with Firebird 1.5. There
is *no* version of the BDE that is warranted for use with ODS 10
databases. The very last BDE driver (5.2, shipped with Delphi 6) has known
bugs with respect to ODS 10 data types. Any client machine having even
older versions of the BDE installed would be *expected* to cause problems.

If you are using an event alerter in your application, you could experience
such periodic crashes if you have clients using the wrong version of the
client library. Any Interbase client library from v. 5.5 forward could
cause this type of crash, even with the "correctly matched" server version.
