Cause

Known issue. This message should be ignored. This is a cosmetic issue that is not meant to be displayed.

Note: After 8.5 RU2 release, these warnings will not be displayed in the agent UI. However, these log entries will be still present as just Informational entry logs. 

In this case INFO message says “Persistent connection is disabled”.

The agent does not try establishing websocket connection, they can check that if they want, but agent needs to check if it needs to establish a connection before doing so and these entries show that agent in fact did check that it does not need to establish websocket connection.

Environment

ITMS 8.5

Resolution

This issue has been addressed with ITMS 8.5 RU2 release. As well further improvements with Persistent Connections has been added to 8.5 RU4 and 8.6 Releases. It is strongly recommended that if you see this type of message to upgrade to a more recent release.
