Symptoms

Configuration validation fails spuriously, including potentially as a result of a ConfigSync or modifying an iRule, with an error similar to the following: 01020036:3: The requested rule (/Common/rule_uses_procs) was not found. Referencing an iRule that previously existed, but has been deleted (or is being deleted as a result of a ConfigSync).

Impact

iRule procs are still referenced after deletion. Configuration validation fails spuriously.

Conditions

-- iRule using procedures in a different iRule. -- iRule attached to virtual server.

Workaround

Force reloading of the MCP binary database. For specific steps, see K13030: Forcing the mcpd process to reload the BIG-IP configuration (https://support.f5.com/csp/article/K13030).

Fix Information
