Yes it is Intermittent. I rolled back the version of Java I was using and haven't had many problems since then. Now I am getting the problem again today and can't login.

I've been getting this error frequently.  The Java console says: [10765 ERROR javawsApplicationMain ClientStartupHelper] Error authenticating with Oberon after successful IMS

I have the same problem, can't access report builder, discover, or the webapp.
