Reload Application Error with 15B.5

Summary

We are experiencing reload application errors with upgrade to 15B.5 - any others facing same?

Hello, everyone.  We had tested 15B.1 thoroughly, with no issues with exception of an error on our Italian career site, which was a showstopper.  So we held for the 15B.5 maintenance pack, which resolved the career site issue.  We did a quick round of "maintenance pack" testing and launched. 

Now that we are live, we have global users reporting a high amount of reload application errors.  Is anyone else on 15B.5 and experiencing the same?  From past history (going way back to Taleo 10 days...) I know these errors can be hard to diagnose/solve.  Hoping to get some collective intel to support.
