Failing DTLS handshakes may cause throttling to block processing of records
Impact
Failing handshakes didn't cleanup counters for throttling. In consequence the threshold may get reached and will not be released again. The results in permanently dropping records. The issues was reported for certificate based handshakes, but it can't be excluded, that this happens also for PSK based handshakes. It generally affects client and server as well.
