Centrify Server Suite 2016 Report Services
Centrify Report Services takes data from Active Directory at a particular point in time, sometimes referred to as a snapshot. The data synchronization service puts the ActiveDirectory data into tables in the reporting database. While performing the synchronization with the Domain Controller, the Data SnapShot Control Panel displays the error: "The server is unwilling to process the request"
The error also appears in the logfile:
[2015-08-21 10:53:25.714 +0800] Centrify.Report.Service.exe[3596,10] Error: SyncServer.DoSynchronization: Failure during synchronize domain a9f1r1.test, DC: a9d1-w2k12r2.a9f1r1.test.
[2015-08-21 10:53:25.714 +0800] Centrify.Report.Service.exe[3596,10] Error: SyncServer.DoSynchronization: Reason: The server is unwilling to process the request.
The issue is due to insufficient memory on the Domain Controller. The DC is unable to allocate enough memory for AD caching.
