Yes, the warning message is generated by the ssl library (see the `add_certs/3'
function in `lib/ssl/src/ssl_certificate_db.erl') and the second message is due
to the fact that adding the certificate failed.
I did a quick search in the bug tracker and I don't think we've seen this
before. As you say, this looks like an OTP issue, so moving the discussion to
`erlang-discuss' would probably be useful.
