Novell ZENworks 10 Configuration Management with Support Pack 1 - 10.2
Novell ZENworks 10 Configuration Management with Support Pack 2 - 10.1
When a server is assigned to do a Wake-On-Lan (WOL) task, the server may experience high utilization or get bogged down when doing other operations.
This is fixed in version 10.3 - see KB 7005455 "ZENworks Configuration Management SP3 (10.3) - update information and list of fixes" which can be found at https://www.novell.com/support
The problem was that the WOL task created multiple items in the zenQueue.
