No, the values are in a backend system I wrote in another programming language (a server). These values change from time to time. I'd like to avoid having to change values in the openacs system (front end) when the values on the backend change. I thought the best and cleanest approach was to make a dynamic proc (the memoized approach one person recommended works also).
At any rate, everything is working fine now. The problem (as someone pointed out) was accessing a system proc when there wasn't a connection.
