Re: [jetty-users] Websocket Cleanup

[Mack Gerhardt <mack@xxxxxxxxxxxxxx>]

I am seeing this in 9.2.11 but I also saw this in 9.3.0. I do see sessions closing and removed but I am seeing a leak where my embedded jetty engine will die on a OOM after about 12 hours of heave use in production. If there is anything I could do or provide please let me know. I was even thinking of recompiling the websocket jar exposing the openSessions so I could attempt to introspect the sessions.

Sounds like a bug.

What version of Jetty are you using?

I am experiencing an issue with a leak of WebSocketSession objects. I believe I might not be closing down sessions properly. I was using the plumbr.eu tool and it detected the following. Any ideas of what should I look for. 

At the time the leak was detected, 30724 objects existed of class

org.eclipse.jetty.websocket.common.WebSocketSession

These objects had been created at

org.eclipse.jetty.websocket.common.WebSocketSessionFactory.createSession(java.net.URI, org.eclipse.jetty.websocket.common.events.EventDriver, org.eclipse.jetty.websocket.common.LogicalConnection):48

and were being held

in array of java.util.concurrent.CopyOnWriteArrayList

  in al of java.util.concurrent.CopyOnWriteArraySet

    in openSessions of org.eclipse.jetty.websocket.server.WebSocketServerFactory
