Upgraded SAM to 6.4 on March 11th. I have been having various problems and have been working with support to get things fixed, but I think all is back to normal now except my database is having problems. See below for a couple of screenshots from DPA. You can see where my wait times jumped up when I initially upgraded. As things were resolved, the wait times were reduced. However, still having problems with my PLE. The PLE hit seems to be tied to a stored proc that is getting executed over 80K times per hour. Wondering if anyone else is having the same problem.
