very good, that's helpful.

It shows that the endpoint is shutdown, but the websocket IOState isn't. (which would be a definite bug)

The openSessions cleanup is (currently) dependent on the websocket layer close (clean or not), however something is occurring that closes the endpoint without the websocket layer being aware of it (it should be aware of it, and trigger a non-clean local-only close on the websocket layer)

In other words, the normal state.
I'm more interested in the ones that stay in the openSessions + has wsSession.isOpen=false
The endpoint.toString() will be most useful to know for those.

For now, I was able to install code into production dynamically to call

if ( !wsSession.isOpen() ){
factory.onSessionClosed(wsSession);
closed++;
}

I am letting it run in production under load, to see how memory usage is, so far in about 10 mins the memory freed up and is running at the levels of a traditional embedded jetty server doing http polling only no websockets.

The raw connection details are missing *groan*, and the ioState is also not present *double-groan*.
Would you mind running a snapshot with some updates to the WebSocketSession.toString() to help use figure this out.
I'm really curious about the raw connection state (will let me know what java/jetty thinks the physical connection is doing), as well as the higher level websocket ioState (let me know what the websocket level thinks is reality).

If you can access the session in that openSession list, can you iterate through them for state information?

A simple toString() on the individual objects in that list should produce reams of useful information.

I'm curious about the various connection and ioState values atm.

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
