Hello

I'm using it with Symfony2.8

gos_web_socket:
    shared_config: true

    periodic:
        - "@app.web_scocket.periodic.reconnect"

    client:
        firewall: [user, main, admin]
        session_handler: "@snc_redis.session.handler"
        storage:
            driver: "@app.web_scocket.storage.driver"

    server:
        host: "%web_socket_server.host%"
        port: "%web_socket_server.port%"

        origin_check: false

        router:
            resources:
                - "@AppBundle/Resources/config/routing/topic/pubsub.yml"

    origins:
        - "%web_socket_server.host%"

    pushers:
        wamp:
            host: "%web_socket_server.host%"
            port: "%web_socket_server.port%"

         "gos/pnctl-event-loop-emitter": "^0.1.3",
        "gos/web-socket-bundle": "^1.7",      

When I push some data to channel sometimes I get error

Connection error occurred Client 3163 not found in vendor/gos/web-socket-bundle/Client/ClientStorage.php line 65

I can't figure why it happened. Will appreciate for any help.
