OK, I've tried a few more things to test what the effects on the problem would be, now I know what the likely cause is.

->Eliminating the read commands did not affect the problem. The script still halts at arbitrary points in the loop even without the 'read from R' element.
->Restarting R at the end of the foreach loop (using the command $R -> restartR();) prevented the random halting. However, as you might expect the script is very slow with this workaround in place, since it has to load R anew with each iteration of the loop.

I am somewhat new to the use of modules in my scripts, and completely so to IPC buffering, so any more guidance you could provide into how to implement the autoflush would be very much appreciated.

Thanks for your help, M
