I have 2 primary servers both recently upgared from 10.0.3 to 10.1 ... however since the upgrade the primary servers will not synch new content / bundles.

Also the second primary server is showing a load of errors in the system information tab in configuration, as below

Full Message: Unable to refresh the system settings from service.
Additional Information: None
Severity: Error
Date: 10 September 2008 10:12:11
Acknowledged Date: None
Message ID: SettingsModule.SettingsRefreshError
Probable Cause URL: None
Log ID: 55f64ed6947deb317d9ca6630761f0cf
Related Objects: None

I have checked the xmd.messages log on the affected server and can see the following errors

[DEBUG] [09/09/2008 06:07:49.846] [1040] [ZenworksWindowsService] [25] [] [BundleManager] [] [An invalid session was passed to GetSessionIdentity] [] []

[ERROR] [09/08/2008 20:07:32.443] [1040] [ZenworksWindowsService] [8] [] [PolicyManager] [PolicyManager.ERROR_NO_DEFINITIONS] [Unable to obtain the policy definitions from the policy service.]

[ERROR] [09/08/2008 17:53:17.568] [1040] [ZenworksWindowsService] [21] [] [Settings Module] [SettingsModule.SettingsRefreshError] [Unable to refresh the system settings from service.] [] []

Anyone have any ideas why this might be happening and any way to sort it?
