Symptoms

Loading of the configuration fail with a message indicating a previously deleted iRule cannot be found: 01020036:3: The requested rule (/Common/rule_uses_procs) was not found.

Impact

iRules are still referenced after implicit deletion (via load). Configuration does not load.

Conditions

- iRule A is calling another iRule B using proc calls - iRule A is attached to a virtual server. - Detaching and deleting iRule A. - Loading the config (or performing config sync).

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

Configuration loading no longer fails when iRules calling procs in other iRules are deleted.
