Upgrade from 10.x fails with the error 'emerg load_config_files: '/usr/libexec/bigpipe load' - failed. -- BIGpipe parsing error (/config/bigpipe/bigip.conf Line 67): 012e0020:3: The requested item (myclientssl {) is invalid (profile_arg ` show ` list ` edit ` delete ` stats reset) for 'profile'."


Unable to upgrade successfully and BIG-IP will be inoperative. You will be unable to log into the BIG-IP GUI. The error signature in /var/log/ltm will exist, and /config/bigip.conf will probably not exist.


Attempting to upgrade from 10.x to 11.6.1 or specific 11.5.3 and 11.5.4 engineering hotfixes with custom Certificate and Key in the clientssl profile.


Delete the following line from all ssl profiles in /config/bigpipe/bigip.conf: inherit-certkeychain false. To complete the upgrade, run the following command: /usr/libexec/bigpipe load. After config load is successful, run the following command: tmsh save sys config && tmsh load sys config.

Fix Information

Upgrade from 10.x now completes successfully with a valid clientssl profile, and produces no BIGpipe parsing error.
