We upgraded from 3.1.0 to 3.1.1 on our AD member server. Since updating it generates "The specified operation cannot be performed due to a busy state or condition. Retry again later." Each time we attempt to update a Folder Target or run a Path Analysis. The engine log doesn't reveal anything that we recognize as a hung or stuck task. We built and patched a new 2008 R2 server and loaded onto that with the same result. Reinstalled and back-rev'd our original server to 3.1.0, still the same result. It's been several hours and whatever is making it unhappy has yet to clear out.
