Broker does not respond to any publisher/subscriber after disconnecting and connecting one client/browser

Hi, I am using apollo broker (Apache ActiveMQ Apollo 1.1-SNAPSHOT) and i have a lot of subscriber. i am using stomp and websocket to feed the message to client. But i am facing two problems:

1. when one client/subscriber is disconnected(browser is closed) once and if he/she try to connect(opening browser and requesting to the broker ) again then broker does not respond to any clients/ publisher/subscriber those were connected to broker.
2. if one browser is flooded with data and can not receive further message then broker stops responding to all clients/ publisher/subscriber.

After restarting broker, it works again . So it is difficult to restart broker repeatedly. I think broker is pointing to the stale connection which has been closed or it is facing problem to maintain connection when one client is trying to reconnect.

can anyone help me? So that all the live publisher/subscriber will not be affected by any one.

Thanks in advance
