What means an error 2 memory full from a call by reference?

[Umi]

I am running an application on a FP-2000 module and call differnt vi from a host.
It works fine for about 3 hours, then I get error 2 memory full from the call by reference node on the host computer.
The application on the FP-2000 still runs.
Labview RT uses about 35000kb of memory on the host.
I am using LabView RT 6.

Any ideas to avoid this error?

I think we need some more information to be able to help you. It sounds to me like it's your host computer that's running out of memory, not your RT module. Is this correct? IF that's so, I'd need some details about what the VI is that you're calling by reference and whether you're calling it on the server or host. Running out of memory on an FP-2000 is no great feat; doing so on your winbox takes a bit more work.

What OS are you running, version of LabVIEW (6i, 6.02, 6.1_, etc?
