for some reason our zenworks server has started to show as busy at our agents.
Code:
 [DEBUG] [06/22/2011 08:33:11.890] [1568] [ZenworksWindowsService] [45] [] [ConnectMan] [] [   Setting IP location https://192.168.xxx/zenworks-zoneconfig/ to retries 7] [] []

Most of the time "zac ref" makes a device refresh in a few seconds while user refresh takes about 500-1000 seconds.

Code:
Agent Status   Version Status 
Asset Management 10.3.3.2458 Running 
Bundle Management 10.3.3.2890 Running 
Content Distribution Point 10.3.3.3582 Disabled
