We have some workflows waiting on approvals. They show business process status = "Running". I read a blog that says wait conditions use resources via the async service (didn't say what: memory? CPU?).
My question is, does a wait condition in a CRM 2011 workflow use resources, and if so, what kind (memory, CPU, or both), and is it significant.
This question is coming up because our async service is spiking up to using over 36 gigs of memory during the day (at some point, the server then crashes).
