Variable engine service crash

[TomasAa]

Okey, I'm using LabVIEW 8.6 with the DSC-module (also 8.6).

I'm working on a supervision project that are making use of a large amount of shared variables which are connected to a remote OPC server. My problem is that the NI variable engine service is crashing, lets say 2 times a week. It seems that it crashes right after i deploy the variables and it does'nt matter if i deploy just 1 variable or 100 variables. After the service crashes it seems that the only way to fiks it is to reinstall labview and DSC. Has anyone encountered this problem before, and is there a way to go around it?

Thanx

Hi TomasAa,

could you provide further information about your system?

Which LV Version, which DSC?

Does this KB apply to your system or solve your problem?

Hey Martin,

So I'm using LabVIEW 8.6 with the DSC-module (also 8.6). Now I have made some breaktroughs, and can reproduce the crash and fix the service "quite" easy.

The variable engine service crashes nearly everytime i deploy variables in SVE, and if it dont crash when i deploy, it crashes after a while. I'm remotely connected to a schneider OPC-server. I can fix the crash by taking both computer of the network and reboot them, though sometimes I have to do this a couple of times before the variable engine service is up and running again.

I have checked the DCOM, SVE and OPCenum settings and they are all running on the same username (with admin rights) as the host.

Any ideas?

Regards,

Tomas
