Unless you're doing something that specifically requires high levels of 
recursion, the default is probably appropriate.  99% of the time this 
error indicates an infinite recursion bug, so increasing the max would 
just postpone the error, not prevent it.  If you are doing something 
with deep recursion, you need to determine its needs and set the option 
accordingly.
