I can't answer your specific question, but I have run into this before and 
ended up using the master script to kick off the slave script (if you know 
what I mean) to avoid this. It was a similar situation involving log 
transfers via scp. I had to break the script up and put the functional part 
on the remote machine itself, then use the cron job on the central machine 
to execute. Makes updates difficult, but it works. Some folks suggested I 
try csh as opposed to sh, but that had no impact. I finally gave up due to 
time constraints, and never got around to fiddling with it any more.
