Looking at our system messages for HFM, we see an error repeating literally thousands of times that says "An Invalid Security Key was Specified". The only the reference I can find to this error is in a patch-set read-me file provided by Oracle. And in that read-me file, all it says is that error was fixed with a patch set that we have already applied. I'm trying to figure out what causes this particular error. It seems to be application specific as I can access all but one HFM application in the impacted environment. Any insight is appreciated.
