> 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 (for me working 100% of
> the time) using android's chrome which also unearth reconnection problem:
> - 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 another 5 seconds there will be a message on both ends about trying
> to reconnect which will result in fast refresh of 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.
> During reconnect attempt there are this error:
