Unexpected response prefix:

Hello, I see in our logs that we sometimes get this response

---> StackExchange.Redis.RedisConnectionException: InternalFailure (None, last-recv: 1391) on localhost:6379/Interactive, Idle/Faulted, last: SMEMBERS, origin: ReadFromPipe, outstanding: 1, last-read: 0s ago, last-write: 0s ago, unanswered-write: 0s ago, keep-alive: 60s, state: ConnectedEstablished, mgr: 9 of 10 available, in: 0, in-pipe: 1391, out-pipe: 0, last-heartbeat: 0s ago, last-mbeat: 0s ago, global: 0s ago, v: 2.5.43.42402

Any idea what does this mean ? \

This is complaining that we didn't understand the response byte sequence - is your setup going through a proxy or load balancer by chance?

If there's more info here, happy to look, but we'll definitely need more info to advise - closing out for now.
