Severity: 4-Minor


Messages are logged as log level 'warning' whenever an SSL connection is terminated and security.fips140.compliance is TRUE or security.commoncriteria is TRUE: -- warning tmm1[12345]: 01260020:4: SSL Connection terminated for TCP <ip_address1> <ip_address2>. These warning messages do not necessarily indicate an error condition; they indicate only that this connection has been terminated.


Cannot determine when unclean SSL-connection shutdown occurs. The system reports as 'warning' messages that potentially should be info-level messages. The messages in /var/log/ltm are generated as warnings regardless of an unclean or clean shutdown. The message should be under level 'info' if SSL connection terminates cleanly, and under level 'warning' if SSL connection terminates uncleanly.


-- SSL is enabled and in use. -- Either db variable is TRUE: - security.fips140.compliance - security.commoncriteria Note: You cannot disable security.fips140.compliance as it depends on FIPS license. If you try to disable it, the system reports an error message: 01070734:3: Configuration error: Change to Security.FIPS140.Compliance DB variable not allowed without a corresponding change in the FIPS 140-2 Compliance license.


Suppress the messages. You can find information on how to suppress specific log messages in K35284961: Filtering BIG-IP log messages :: https://support.f5.com/csp/article/K35284961, in the section: Creating a filter that prevents specific messages from being sent to the local log files.
