This update should only be applied if the symptoms above are being experienced, and are causing problems.
If it is not possible to implement ZCM 11.2.1 Monthly Update 1 at this time, 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=zKtdNWriegU~ as "ZCM 11.2.1 fix for ZCM 11.2.1 agents cause high server utilization - see TID 7010585". This Patch is recommended for all ZCM 11.2.1 zones with more than one Primary Server, that have not deployed ZCM 11.21. Monthly Update 1 or later
Workaround: Temporarily location rules to exclude all but one primary server for just the configuration role and not use default rule. After the fix is applied, that should be changed back to the original settings for proper load balance and failover.
