Subject RE: [IBO] Re: IBO 5.2.0.7 and strange error on connect to the server
Author IBO Support List
Ok, I have been working with Magnus in Sweden and we have 100% solved this
issue.

The fix will be in Build 8.

If anyone would like the simple patch to apply to your current sources, here
it is:

In TIB_Transaction.API_Start find this code that looks like this:

While ( ErrCode <> isc_conn_lost ) and
( ABS(GetTickCount-2000) > Abs(ticks) ) do
ErrCode := isc_start_multiple( ... )


What needs to happen is to simply remove the while loop and leave just the
call to the API.

For some reason, the way this loop was coded, it completely skipped making
the API call.

This is old code to deal with IB 4.x or IB 5.x instability to auto-recover
from something quirky. I am just going to strip that out.
