Puzzling "Execution halted"

I wrote an R program that does heavy computations with hundreds of lines of code. It's running fine both interactively and in batch mode on a Mac OS X computer. The program also has no problem running on a Linux system (Fedora 14) interactively. However, when I try it on the terminal in batch mode on the Linux system, it chokes in the middle of the computation with the "Execution halted" error message. I already put try or tryCatch in those places where computation may throw an error. And the warnings are set in default (options(warn=1)). I wish I could provide the code for help, but that seems impractical. How to debug this?
I think you have to use the old-fashioned way: sprinkle print() or cat() statements through your program to identify where the error is happening. Duncan Murdoch
