    Fixed problem

    Problem Short description Description Steps to reproduce

    Application Manager

    PRB1986694

    		 App Manager and My Company Applications incorrectly shows available updates after Update Checker

    CMDB Query Builder

    PRB1977703

    KB2727703

    		 Query Builder in V2 mode can cause memory issues due to a static variable An internal variable which is declared as static keeps being appended and thus creates a large memory footprint. 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

    		 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.
