Problem

The Cisco Unified Contact Center Express or IP IVR 7.0(1)SR2 release contains behavior that can affect your release 7.0(1)SR2 deployment. The IP IVR\Unified CCX 7.0(1) SR2 build posted to the Cisco Download Software page on 4/30/09 was recalled on 06/23/09. The 7.0(1) SR2 is no longer available for customers to download.

Release 7.0(1)SR2 Issues: These issues have been identified and can impact your deployment:

  • CSCsz47854 (registered customers only)

    Symptom: There is a defect in the underlying third-party database driver (jtds driver). This defect can result in increased CPU usage over time and can bring the system down after some weeks (dependent upon the load on the system).

    Conditions: This issue appears on systems with high call volumes and sustained agent traffic for more than 2-3 weeks.

    Workaround: Cisco recommends that customers on 7.0(1)SR2 use Perfmon in order to monitor CPU usage for the overall system, as well as the iscoUnifiedCCXEngine process, and then reboot the system within maintenance hours if the system shows a steady increase.

  • CSCta33316 (registered customers only)

    Symptom: A deadlock in the engine can occur that causes the engine to be automatically restarted. In case of high availability (HA) deployments, a failover occurs.

    Conditions: An intermittent race condition that can occur in scenarios which involves multiple call legs, such as agent transfers.

    Workaround: No manual workaround is needed. The system detects the deadlock and automatically restarts the engine. For non-HA systems, affected services are automatically restarted. HA systems fail over to standby.

Solution

Cisco recommends that you download and deploy 7.0(1)SR3. Visit the Cisco Download page in order to download the Cisco Unified Contact Center Express or IP IVR release 7.0(1)SR3:
