The ones we encountered had mostly to do with accessing databases on different hosts... We were able to fix our problem by using c4gl to create c-compiled executables instead of using the RDS p-code and the runner, which is a good idea for production systems anyway. In other words, the same program that would NOT run using the runner DID run after being c-compiled. A word of caution though... RDS is very forgiving on both variable initialization and conversion between types. If you do c-compile your programs, you should check them to make sure that all variables are initialized, and that you're not passing an INTEGER variable to a function expecting a CHAR, or anything silly like that. If this option is available to you, I would suggest you try it. If not, I would strongly consider making it an option.
