Hi all.

I've installed Firebird 2.1.4 x64 on a machine with the following
features.

Windows Server 2008 R2 Foundation Service Pack 1;
Intel Xeon CPU X3430, 2.40GHz;
RAM = 8 GByte;
64 bit OS;
Hard disk = 136 GByte;

Sometimes, about 3 times per week, the Firebird server crashes with
following error:

IPVSRV (Client) Fri Sep 02 17:58:04 2011
"C:\Program Files\Firebird\Firebird_2_1\bin\fbserver.exe":
terminated abnormally (4294967295)

Immediately the Firebird Guardian restart the Server, but it's to late: my
application crashes too.

The clients (all written in Delphi) which are linked concurrently to the
server is about 5 or 6 every times (very small number....).
There's a data syncronize service that works with dbExpress technology via
dbexpida40.dll ad more occurrence of an application working with the old
BDE technology (it can't be still migrated to dbExpress :-( ....).

I'd like to study in deep the error, but I don't know if Firebird has a
verbose log funcionality. How can I activate it?
I can't reproduce the error because it's very sporadically.

Thank you for every idea or, better, solution that you can give me.

Best Regards.
