This occurs even if the Engineering Hotfix includes the fix for ID2296269 - This may cause other operations to fail, such as updating any components that would require available space in the /usr volume The lack of available /usr volume space may also cause internal process failures, which would block the release of BIG-IP v17.5.1.6 Engineering Hotfixes.
