DoS due to excessively large websocket message in ws
Affected versions of `ws` do not appropriately limit the size of incoming websocket payloads, which may result in a denial of service condition when the node process crashes after receiving a large payload.RecommendationUpdate to version 1.1.1 or later. 
Alternatively, set the `maxpayload` option for the `ws` server to a value smaller than 256MB.
