Description of problem:

Several of our nodes have seen frequent node-web-proxy crash/restarts with the following traceback (or something similar. WebSocket.send line 175 is always the location of the exception):

/usr/lib/node_modules/ws/lib/WebSocket.js:175
    else throw new Error('not opened');
               ^

DEBUG: Program node /usr/lib/node_modules/openshift-node-web-proxy/bin/web-proxy.js --config /etc/openshift/web-proxy-config.json exited with code 8

This error seems to be because the connection to the backend server has been closed unexpectedly.
