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?</div><div><br></div><div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 11px/normal Monaco;
