ERROR
SSL Handshake: Disallow ClientKeyExchange. Closing down SSL
connection
The SSL connection will be closed because there are not enough
resources to process any ClientKeyExchange messages at the
moment. This could be a result of SSL handshake message flooding.
This action is triggered by a system that monitors the amount of
resources that is spent on key exchanges. This system is controlled
by the advanced setting SSL_ProcessingPriority.
ssl_close
Investigate the source of this, and try to find out if it is a part of a
possible attack, or normal traffic.
