[Maintenance Job Name] Cleanup Inactive Workflow Assemblies [Purpose] Seeks custom workflow assemblies that are no longer referenced in workflow rules or in-process jobs. Those unreferenced assemblies are then deleted. Consider the scenario where you register version 2.0 of a custom workflow assembly. You may update your rules to reference the new version, but some in-progress jobs may still be referencing version 1.0. Once those jobs have completed, this maintenance job will clean up the version 1.0 assembly that is no longer referenced by rules/jobs. It executes the p_CleanupInactiveWorkflowAssemblies stored procedure.
By default, the job executes every 24 hours, reschedule the job to run at non-peak hours. E.g. 11:00PM at night
