----------------------------------------------

             Summary: Growing list of stream connection in admin->connections
                 Key: OPENMEETINGS-2355
                 URL: https://issues.apache.org/jira/browse/OPENMEETINGS-2355
             Project: Openmeetings
          Issue Type: Bug
          Components: Room
    Affects Versions: 5.0.0-M5
            Reporter: Konstantin Kuzov
            Assignee: Maxim Solodovnik
         Attachments: stale-processors.png

After [OPENMEETINGS-2315] and [OPENMEETINGS-2316] some stream connections states not terminating fully and there are growing list of stale streams in admin->connections (look at stale-processors.png).
It happens randomly, most likely due to unreliable network, slow devices or browser quirks.
I found the only one reliable way to reproduce this using android's chrome:
 - enter the room with one another participant
 - not closing tab with om, just switch to another tab with random page. Another participant will see frozen image.
 - wait around 10 seconds and switch back, on your end you will see fully working webcam, but on participant's end the image will still be frozen.
 - after around another 5 seconds there will be a message on both ends about trying to reconnect which will result in fast refresh already seamingly working camera on android chrome, but on another participant there will be only empty window with avatar. And it will stay that way forever. At that point android user can exit the room and his stream will stuck.
