Environment

Novell ZENworks 11 Configuration Management
Novell ZENworks 10 Configuration Management with Support Pack 3 - 10.3

Situation

Server holding ZCM database has high utilization.

ZCM Primary server service-messages.log shows a large amount of getContentInfoEx requests.

Agent debug logs show agent re-caches content that is already cached.  The agent zmd-messages.log will show duplicate requests for the same content each time the agent refreshes.

Resolution

For ZCM 11: This is fixed in version 11.1 - see KB 7008746 "ZENworks Configuration Management 11.1 - update information and list of fixes" which can be found at https://www.novell.com/support

For ZCM 10.3: This is fixed in version 10.3.4 - see KB 7008244 "ZENworks Configuration Management 10.3.4 - update information and list of fixes" which can be found at https://www.novell.com/support

Additional Information

Steps to reproduce
  1. Create a bundle with content (install files or directory works well)
  2. Create a second bundle with the same content (give server time to import content and replicate to any other necessary servers)
  3. Assign the second bundle to a workstation
  4. On the agent, set log level to debug and do a refresh
  5. Verify in the agent logs that it queried for the item info for the second bundle (you should see a line like "Content service returned info for item Item info for {guid}" the guid should match that of the second bundle
  6. Do another refresh and verify it again requests the item info.

The agent will request the item info each refresh, which causes a lot of unnecessary lan traffic, server and db load.
