Those having this problem, please make the following changes in your source,
recompile your packages/projects and let me know what the real message
should be that led up to the false reporting of an ErrCode 0 error.


function TIB_Transaction.CheckLostConnection: boolean;
var
ii: integer;
tmpErr: longint;
tmpStatus: status_vector;
begin
Assert( Assigned( IB_Session ));
tmpErr := IB_Session.ErrCode;
tmpStatus := IB_Session.Status;
try
Result := ConnectionLostErrcode( IB_Session.ErrCode );
if Result then
begin
FServerConnectionWasLost := true;
if ConnectionCount = 1 then
Connections[0].SetLostConnection
else
begin
for ii := 0 to ConnectionCount - 1 do
begin
Connections[ii].VerifyConnection;
end;
end;
end;
finally
IB_Session.ErrCode := tmpErr;
IB_Session.Status := tmpStatus;
end;
end;

Thanks,
Jason

Ops! Mee too!

Same scenario: A client windows small business server 2008. Affects the
IB_FTS Util and my FTS indexing service on that machine. Tried to fiddle
with the connection parameters to no avail (localhost/127.0.0.1/DNS Name)
alias or path. No go.

The Util is 32-bit and the service is 64-bit. Same diagnose.

I can not restart the server from here, but i'll ask the on-site people to
do it when possible.

Oh, and i too accessed the clients using Terminal Sever.

Regards,

/Dany
