Resolution

This is fixed in version 11.4.2 - see KB 7017469 "ZENworks Configuration Management 11.4.2 - update information and list of fixes" which can be found at https://support.microfocus.com/kb/doc.php?id=7017469



Workaround
Stay logged into ZCC while content is importing to the primary.  See also

If using zman bc or pc to create bundle or policy with content, use start-shell-as-service to keep zman logged in during content import.
..."

Cause

Uploaded files get removed before they get imported to the content repository if  and when the ZCM administrator ZCC session gets ended by logout or timeout before the content import finishes. This is caused by a server internal issue of handling the uploaded files which relates them to the admin user session.

Additional Information

When content is uploading, it is temporarily copied to a sub folder of the tomcat temp folder
  • Linux: /var/tmp/
    or /var/opt/novell/zenworks/content-repo/tmp
  • Windows: %zenworks_home%\share\tomcat\temp\
 which gets named by a GUID number.

Also a <GUID>.import file is then created under:
  • Linux: /var/opt/novell/zenworks/content-repo/content/importData/
  • Windows: %zenworks_home%\work\content-repo\content\importData\

The importData directory is monitored by the zenloader service for <GUID>.import files. When it finds one, it tries to import the respective content located in the tomcat temp folder. If the required content is not found, it errors out but does not delete the <GUID>.import file. It just keeps trying and failing. Once bad <GUID>.import files have been identified, they can get manually removed to stop this cycle.
 
Per development, this can be duplicated with even a single file in the uploaded directory.
