Are unattended nodes included in the limit of consecutive chained nodes?

Question

Activity chaining will break if: "The number of unattended nodes that exists between two (attended) activity-chained tasks surpasses the (default) maximum number of 50" Start and end events are not attended/unattended, so are they not included in the total? Subprocess nodes are attended/unattended, so is there a potential design cost to nesting subprocesses? ...

I had a similar issue not long ago. Here's the link to the conversation forum.appian.com/.../e-67771 The short answer is yes, unattended nodes are included in the count. Because my case varied widely in how many instances some nodes are running I built a waiting screen that checks a status variable to clear before moving forward. When I get the time, I plan on reevaluating my process to avoid running multiple instances all together. Another option is to increase the chained node limit.
