Hi Gareth,

Have you examined what is happening in the API trace log provided by the
IB_Monitor?

I'm wondering if the cause of the problem would show up in that. You could
have something in the environment that IBO picks up on that is throwing a
kink in things.

Subject: [IBO] Re: IBO 5.2.0.7 and strange error on connect to the server

Hi,

I have also had sporadic issues with this problem in our internal testing.

Here are our observations:
- We are currently using IBO-5.2.0 Build 6.
- It can happen when connecting to a Firebird server using TCP and when
using Firebird in embedded mode.
- Once this happens, the only way to get applications that use IBObjects to
connect to databases again appears to be to restart the computer. Neither
restarting the application nor reinstalling the application make any
difference.
- Once this happens, our applications cannot connect to local or remote
databases and both network and embedded Firebird connection attempts throw
the same "ISC ERROR CODE: 335544648 unknown ISC error code 0" exceptions.
- FlameRobin running on the computer experiencing the issues can connect to
both local and remote databases without issue.
- Our application running on other computers can connect to the Firebird
server running on an affected machine without issue.
- In one case, this happened after the user logged in to their computer via
remote desktop, and we aren't sure about the other cases.

Any advice on resolving this issue would be appreciated.

Regards,
Gareth Marshall
