This would happen if one or more queries are executed enough times to bloat this variable. | Refer to the listed KB article for details. | | Database Persistence - Data Management PRB1988503 [KB2764725](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB2764725) | Active subflow executions with clean parent flow executions are listed as 'Unreferenced Records' and are deleted by DMUnreferenced RecordCleaner | This issue was observed in Zurich. If a parent flow completes while an associated asynchronous subflow continues running, the completed parent flow context is cleaned up by the retention policy by routine system cleanup. As a result, the running subflow becomes unreferenced, and may be removed during routine system cleanup. | Refer to the listed KB article for details. | | Flow Engine PRB1935825 | Skip_schedule_cleanup is not reset to false for subflows | The table cleaners need to be revised. | Open http://localhost:8080/ sys_auto_flush_list.do? sysparm_query=conditionsLIKEskip _schedule_cleanup \&sysparm_view=. Observe that all the table cleaners use skip_schedule_cleanup. Skip_schedule_cleanup should be managed well. | [ ] {#zurich-patch-6-hf-1__all-other-fixes} ## Fixes included {#zurich-patch-6-hf-1__section_tbk_mvb_g3c} Unless any exceptions are noted, you can safely upgrade to this release version from any of the versions listed below.
