What would cause an RT Single-Process Shared Variable to return an Error 42?

[WNM]

On a cRIO-9024 (RIO v12.0, LV v11.0.1f2) when I try to load an initial value into a single-process single-element RT-FIFO UInt32 shared variable (no timestamp), I get the following error from the shared variable:   Error 42 occurred at Shared Variable,  Possible reason:  LabVIEW:  Generic error.

Does anyone know what might cause this?

Hi,

One solution is was to monitor the memory and CPU usage on the cRIO when you try to deploy the variables. There is a chance that you are running out of memory when the variables are deployed. You can monitor the memory/CPU usage in the Distributed System Manager
This problem was solved (years ago) by reformatting your cRIO device.
