Puzzling "Execution halted"
Thanks for the pointer! Unfortunately it doesn't look like a memory issue: /var/log/messages contains nothing about memory problems. And the Linux system has enough RAM for this computation. Gang

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?
Have a look at your /var/log/messages: it might well be the out-of-memory killer killing your R process because it eats too much RAM... My two cents
