Problem Cause

StoreFront cannot perform a successful synchronization between the StoreFront Servers Group. The service, which handles the replication is stopped. Errors will be logged inside Event Viewer > Citrix Delivery Services.

Following are the detailed information about the errors:

Scenario - 1

Error occurs on Primary StoreFront Server:

Three errors will be logged in Citrix Delivery Services Logs (Event ID 0, another Event ID 0 and a third one Event ID 1 with task Category 2850).

Error - 1

Event ID 0 Task Category: None

Error - 2

Event ID 0 Task Category: None

Note: It is a replica of the first error.

Error - 3

Event ID Task Category: 2580

When there is an error on Primary server, the event logs shows the URL http://localhost/Citrix/DeliveryServices/ConfigurationReplication.

Using this, you can determine the problem which is related to the Primary Server pushing all StoreFront changes/Settings/Replication.

Scenario - 2

Issue can also be observed when replication service is not working on a remote Server. The Primary StoreFront Server also throws errors.

Error - 1

Error - 2

Error - 3

Note: Server 1 is unable to get sync update to Server 2 because replication on Server 2 is not reachable.
