Two thoughts:
1 - If any jobs involve scanning directories on the same physical device,
run those sequentially or you'll probably just end up thrashing the

2 - If you already have the Korn Shell installed, try using that;
the commands you showed worked just fine when I tried them on
KSH version 93u+ 2012-08-01.
