I am installing an Oracle 22.214.171.124 Enterprise Edition on RHEL 6.4 I set it up with ASMM and HugePages (64G of RAM)
There may be a correlation between the errors and signing in to em express (not 100% certain yet). I mention this because of the following blog post with a similar error: http://surachartopun.com/2013/06/learn-something-wtih-12c-and-enjoy-bug.html
I have opened an SR already but wanted to see if anyone had thoughts on this.
