## Fixed problem {#zurich-patch-3-hf-2__section_u4m_jcf_hhc}

{#zurich-patch-3-hf-2__all-other-fixes__entry__4}

| Problem | Short description | Description | Steps to reproduce |
|-|-|-|-|
| Configuration Management Database (CMDB) PRB1949356 | Exact count match check results in an incorrect duplicate task creation | After upgrading to Zurich, de-duplication (dedupe) tasks are created incorrectly under certain scenarios. As a result, a large number of records are created in the duplicate_audit_result table, causing significant database growth. Instead of updating existing entries, new records are inserted during each subsequent run. In one scenario, the de-duplication tasks are created when they were previously working. In another scenario, users with many hosts that contain cmdb_serial_number records with the same serial_number and serial_number_type notice that the number of duplicate_audit_result can grow to be tens of millions daily. |   |
