I believe the property you want to set is: ecf.remotecall.timeout...i.e.:

-Decf.remotecall.timeout=40000

This property is documented in [1].  We should have a single wiki page 
enumerating all the properties (and default values) for remote services, 
but we do not have it yet.  If you (or someone) would like to create 
such a page, I will add to it.

Could you present an example of the BrokenPipe exception output that you 
are referring to?  ...and you mean just to prevent the exception/stack 
trace info from going to the log...is that correct?

Thanks,
