    Fixed problem

    Problem Short description Description Steps to reproduce

    AI Search

    PRB1836358

    KB1790348

    A race condition causes an incorrect deleteMultiple() query to be generated on the v_search_genius_result and sys_variable_value tables

    When the AI Search Genius Result is requested and processed in a multi-threaded, high-concurrency environment, such as when multiple users simultaneously perform search functions on a portal or Virtual Agent (VA), a thread safety issue arises. This issue may cause an incorrect deleteMultiple() query to be generated, potentially leading to the deletion of excessive records from the sys_variable_value table. This may result in unexpected outcomes for various components including the Integration Hub, Service Catalog items, and workflows due to the absence of these critical records.

    Refer to the listed KB article for details.
