Websocket connection failed. Received start of new message but previous message is unfinished

[TkNeo]

We have been using the angular-websocket library for months and love it! Recently ran into an issue where we are asking for data that our server is sending in 7-8 frames. There are multiple such requests (8 or so). Nothing too heavy .But we have started to get this error saying "Received start of new message but previous message is unfinished". I am wondering why this is happening ? This does not sound like an edge case load ? And what can we do to fix it ?
