After suffering for the last 2 to 3 months with longer and longer slowdowns with my current version of EIS7, I finally got around to looking up an answer on the web. After reading the above info, I also shut down HIPS and rebooted 2x. After doing so, my long shut down time (sometimes up to 5 minutes) has gone away and I am back to the normal 15 seconds or so. I had my HIPS in the interactive mode, and have not tried it in the auto mode to see if the long shutdown continued.
