lots of Exception in the zookeeper.out

Hi
Our cluster contains 3 nodes and works well in most time. But there are lots of below exceptions, and some time the ephemeral node is lost but the register process still alive. Any hint of this issue?

EndOfStreamException: Unable to read additional data from client sessionid 0x146b25b8d5b007e, likely client has closed socket
