After an upgrade, configurations with DoS rate thresholds set may fail to load with a "Rate threshold cannot be set to 0" error message in /var/log/ltm.
The BIG-IP will fail to load the configuration.
DoS Protection configured with rate thresholds on a pre-12.0 installation. Upgrade to 12.0 and above.
Manually edit bigip.conf and remove all DoS rate threshold settings. Once the configuration successfully loads, apply the desired rate thresholds.
