Whew. What a relief.
From the title "fatal error" thought you had sold off your wife's Lexus convertible and bought yourself a pair of 150 pound monoblocks.
Fatal error
Yesterday I came across the fatal error that would prevent me to access databases from the console. I've started calling tech support and figured out that input stream pops up with invisible character(s) that need to be cleared after an input of Data Base ID before pressing an Enter key.
It was invisible bug -- a Ghost In The Machine.
