Environment

Novell ZENworks 10 Configuration Management

Situation

When Patch Management remediation bundles are deployed with the schedule of "Now", instead of  n number of QuickTask refresh actions sent (where n is number of devices) the number of QuickTasks sent is n squared. 
 
In large environments, with many devices selected to receive remediate bundle, this can cause high utilization on the ZENworks server and may consume excessive bandwidth.

Resolution

A fix for this issue is included in ZENworks 11, see KB 7006995 "ZENworks 11 - information and updates" which can be found at https://www.novell.com/support

This is fixed in version 10.3.2 - see KB 7007237 "ZENworks Configuration Management 10.3.2 - update information and list of fixes" which can be found at https://www.novell.com/support

Workaround: if it is not possible to upgrade to 10.3.2 at this time, in the interim, Novell has made a Patch available for testing, in the form of a Field Test File (FTF): it can be obtained at https://download.novell.com/Download?buildid=qWx_LgjvY9A~ as "ZCM 10.3.1 high utilization when Patch Bundles have schedule [now] - see TID 7006621". This Patch should only be applied if the symptoms above are being experienced, and are causing problems.
