[rules-users] stack overflow in work items

[Garrett Conaty]

My scenario is a rule that is firing over a collection.  For each item  
in that collection a ruleflow starts to handle it.  Right now the  
ruleflow just uses the log workitem to log the steps.  When there are  
~600 items in the collection I'm getting stack overflows.  Granted the  
processes could be optimized (I'd really like to take each thing in  
the collection that matched and start a process for the set of them).   
Still is there a limit to the number of active processes with work  
items?
