Debugging SAS error message "ERROR: Cannot retrieve metadata from SAS Metadata Repository."

I get the above error when submitting code as follows:

337   data x;
338   set nz.aa;
ERROR: Cannot retrieve metadata from SAS Metadata Repository.
339   run;

The NZ library is on a Netezza server accessed via UNIX (libname engine), SAS 9.1.3. Our signon script is automated and not easily v开发者_如何转开发isible.

What is the most likely cause of such a message, and/or how can further detail be obtained?

I'd first check to see that the user running the code has permissions in metadata to read the library. That seems the most likely culprit to me.
