I found a thread from 2004 which implies that this condition
typically happens when the SSH client machine's user has
a .ssh subdirectory (and/or files in it) which have the wrong
ownerships and/or permissions such that the public key
cannot be read and usually the remote host key cannot be
written to the file with the list of known hosts either.
I'd look for the ~/.ssh of the initiating user on the client side
to be owned by someone else (e.g. root rather than oracle)
and possibly read/write permissions set incorrectly as well.
