NIFB, Lookout hangs with OPCclient

[Robin]

Running NIFB 3.0 with PCI FB card under Win2K. With Lookout V5.1 running OPCclient, the application frequently hangs. The point it hangs varies. I tried running Server Explorer and it also hung after a time. After Lookout hangs, sometimes the NIFB process is at 99% CPU utilization and sometimes at 0%. The FBUS Dialog Utlity works fine, so the problem appears related to OPC. Unfortunately Lookout doesn't support the PCI FB board directly so we have to use OPCclient.

Lookout 6.0 Development/Runtime server (unlimited)…. I use an OPC server as a driver in my server-process. I created several client processes on the same machine. I was going to load one of the client processes by request and read appropriate information. When I tried to load one of the client processes my PC was hanging for about 40 second. I.e. loading takes me much time.  I’ve red that this hanging could be concerned with BAD OPC-connection. All of my connections are ok!!!  I’ve decided to run all of my client processes and call an appropriate “panel” of that processes to get concrete dates. Is it advisable to use several concurrently running processes? All of it’s objects are only minimized but its are online. What is the cause the PC to be hanging?
