One or multiple Analytics features fail to start

Affected versions

From DataMiner 10.2.0 [CU13]/10.3.0 [CU2]/10.3.5 onwards.

Cause

During the startup of DataMiner, there may be a connection drop between SLAnalytics and SLNet, which can lead to a failed database read before the connection is recovered.

Note

This issue is isolated to DataMiner Analytics features and does not affect any other functionalities.

Workaround

Restart the SLAnalytics service (e.g. via the Task Manager) after DataMiner has successfully started up.

Fix

Install DataMiner 10.3.0 [CU12] or 10.4.3.
