But I don't know what's causing them or how to fix them?

I running RavenDB though IIS on a windows 2012 VM in azure using build 35181 of 3.5 

annoyingly RavenDb keep's saying that I don't have WebSocket protocol; But I know I categorically do. I have yet to debug it and work out why that's playing up.

Any guidance or recommendations welcome

Thanks

The first one is likely something that happen while you are shutting down RavenDB.

The second is because you aren't running as admin, which is fine and handled.

What do you mean WRT websockets?

Ah i see yes azure dose shut down its services over night to save costs so that would explain it, Is there a way to ensure ravenDB has admin rights , I added the IIS worker process to the admin group, should that do the trick?

The WebSocket error get is:

Your server doesn't support the WebSocket protocol!
EventSource API is going to be used instead. However, multi tab usage isn't supported.
WebSockets are only supported on servers running on Windows Server 2012 and equivalent. 
 If you have issues with WebSockets on Windows Server 2012 and equivalent use Status > Debug > WebSocket to debug.

I know i have web socket installed and setup in IIS 7 so not sure why its saying its not enabled ?

What does  Status > Debug > WebSocket tell you?

Here is the debug from Raven and screen grab to show web socket is enabled though IIS 8

Connecting to web socket using url: ws://51.141.10.9/databases/RavenDB/websocket/validate?singleUseAuthToken=b8f387c1-1b82-4b5f-bf8b-d19bb5400ee4&id=test&coolDownWithDataLoss=1000&isMultyTenantTransport=false
Server doesn't support web sockets protocol
WebSocket disconnected in unclean way

Try using a WebSocket client to see why it isn't connecting properly.
