We see exactly the same behaviour in some of our applications. Has there not been any response to this at all?

I observed the same behavior. I think the reason was that the idle connection was terminated by the server but the Java application doesn't clean up idle connection. So it kept using the expired connection, which resulted in this error. I've tried the solution in https://programmerah.com/solve-the-unexpected-end-of-stream-exception-thrown-by-jedis-536/, but didn't solve the problem. Please help!
