> Continuous increase of websocket connections in Ambari web UI
> -------------------------------------------------------------
>
> Key: AMBARI-25928
> URL: https://issues.apache.org/jira/browse/AMBARI-25928
> Project: Ambari
> Issue Type: Technical task
> Components: ambari-server
> Affects Versions: 2.8.0
> Reporter: caijialiang
> Priority: Major
> Attachments: image-2023-04-14-14-48-36-956.png,
> image-2023-04-14-14-54-25-386.png
>
> Time Spent: 2h
> Remaining Estimate: 0h
>
> How to reproduce: Open Ambari UI page and use Chrome to view the websocket
> connections. At the beginning, there is only one connection. After a few
> minutes, it is observed that the connections keep increasing infinitely. If
> the page is refreshed, the number of connections will return to one, and then
> continue to increase.
