I did mentioned above that "python myscript.py" did run on the command line 
but hung in Zope, or are you referring to something different by "Python

I had my threads set to 10 but have upped them to 16 to see if that will make 
a difference, thanks.  I've also upped the pool size because of several 
instances of

pool_size of 7

in the event log.

Thanks,

Thomas
