If a BIG-IP is on version 13.1.0 through 15.1.x and has profiles in use that use wam-tcp-wan-optimized and/or wam-tcp-lan-optimized as parent profiles, then when the configuration is upgraded to 16.0.0, the configuration fails to load, with an error similar to: err mcpd[10087]: 01020036:3: The requested parent profile (/Common/wam-tcp-wan-optimized) was not found. On devices that are provisioned with not just the LTM module this may lead to an out of memory condition as the config load failure prevents memory provisioning completing leaving too little 4KB page (host) memory and too much huge page memory. If suffering memory pressure then management access to device will be sluggish or not possible.
Configuration does not load.
-- Upgrading from version 13.1.0 through 15.1.x. -- Using profiles derived from wam-tcp-wan-optimized and/or wam-tcp-lan-optimized.
Remove these profiles and adjust the configuration elements that use them accordingly. If it is difficult to work on the device it may be necessary to rollback to earlier version and make changes there. Usually it would be better then to delete newer software volume and reinstall it at which point the modified config will be copied across and installed on newer volume. Here are two examples: -- Copy the definition of 'wam-tcp-wan-optimized' from /defaults/wam_base.conf into /config/bigip.conf, and then reload the configuration. -- Change the references to wam-tcp-wan-optimized to something else in your config file (e.g., tcp-wan-optimized), and then reload the configuration.
