Novell ZENworks 10 Configuration Management with Support Pack 2 - 10.2
After migrating applications from ZDM 7 to ZCM and assigning to devices, zenworkswindowsservice.exe consumes large amounts of memory (for example: 1.2GB of RAM) on the managed devices with these bundle assignments. In some cases this can result in OutOfMemoryException.
This is fixed in version 10.2.2 - see KB 7004803 "ZENworks 10 Configuration Management 10.2.2 - update information and list of fixes" which can be found at https://www.novell.com/support
Workaround for prior releases: For complex applications, deselect the "Migrate distribution options as individual actions" option. This will convert the AOT to MSI and not individual actions. See Best Practices section E.4 Migrating Applications as Actions or MSI at https://www.novell.com/documentation/zcm10/zcm10_zen_migration/data/bg9ljj5.html
