Opened: Jan 31, 2018 Severity: 3-Major
SSL/TLS handshake failures and terminations are being logged at too low of a level (INFO).
Sometimes other errors are produced, and the cause is a SSL/TLS handshake failure, but this failure is not being logged.
-- SSL/TLS connections are received or sent. -- Handshake failures are logged.
There is no workaround.
SSL/TLS handhake failures and terminations are now logged at a higher level (WARNING).
