In recent months I started noticing a new type of log message. Here are some examples. One of each but my logs show many runs of these types of messages. Along with others but these are the majority type. Imagine lines like these repeated many times in the syslog.

Team, We upgraded sshd in our product from OpenSSH 8.6 to OpenSSH 9,.6. After the upgrade, clients are seeing significant increase in time to do ssh to the listener.
