Alert description: Active Directory Domain Services could not update the following object in the local Active Directory Domain Services database with changes received from the following source directory service. Active Directory Domain Services does not have enough database version store to apply the changes.
Restart this directory service. If this does not solve the problem, increase the size of the database version store. If you are populating the objects with a large number of values, or the size of the values is especially large, decrease the size of future changes.
Reboot will clear the version table but it does nothing to identify or resolve the core issue.
The version store has reached its maximum size because of unresponsive transaction. Updates to database are rejected until the long-running transaction is omitted or rolled back. TechNet suggested looking for event IDs-1022, 1069,623 and none of these event ids could be found in event viewer.
Below is the solution but it is your own risk to change registry setting.
Backup the Registry before Proceeding
- Update ‘Version Store Size’ (the Ops Mgr Agent queue/cache Db) by using Regedit to change “HKLM\System\CurrentControlSet\Services\HealthService\Parameters\”Persistence Version Store Maximum”.
Value should be 5120 (decimal) (equates to 80MB).
- Update value for ‘MaximumQueueSizeKb’ in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HealthService\Parameters\Management Groups\<ManagementGroupName> Value should be 102400 (decimal)
“Please reboot the server”
Check in the Event Viewer for Event ID 1394 “All Problems preventing updates to the Active Directory Domain Services database have been cleared. New Updates to the Active Directory Domain Services database are succeeding. The Net Logon service has restarted”
You can find this event in “Directory Services” Log of the Domain Controller.
