Lookout Logos ressource problem

Hi,

I have encountered a very weird behaviour using Lookout. We have a server (quad xeon 700) using a dual port intel networking card. Since we had some problems with one of the server we tried to use a backup server that is identical. Once we'd setup it (same configuration as the old server) we had a problem with Logos ressources.

- The first time we boot the computer Lookout was working. We have a monitor interface and everything was running, the console were communicating with the server.
- We use a Datasocket link between a LabVIEW server and the Lookout server on the same computer. When we start the communication between them Lookout crash randomly, no error messages.
- After a crash there is "red X" on the monitor screen and the
Lookout server Logos ressources are not accessible. What I have tried to do is to re-link the object that as "red X". It worked but when I restart Lookout the new objects have "Red X" on top of them.
- The following action make Lookout works again : Change the Network configuration (Unregister and register them back to the domain), Re-install Lookout, Re-install LOGOS. But when LabVIEW communicate with Lookout the same problem occur again.

I know that it looks very strange and I don't expect that someone else had this problem before. This system works on the other server (we have put it back and everything works fine except for some bugs). I wonder if someone could have an idea of items I could check.

Any help appreciated!

Thanks a lot!

Thrawn,

We need a little more information on your situation. Please indicate your software versions (Lookout and Logos) and Operating System of both PCs. Was the Datasocket connection in LabVIEW DSread, DSwrite, or front panel? Are you using the OPC protocol or the Lookout (logos) protocol? If you have not already, try connecting to the Lookout OPC server using Server Explorer. What is the result?
