Hello!
We have Apache ignite cluster v2.7 with Zookeeper discovery. After some
time in the log on each node appeared these messages:
[2019-03-21T22:48:35,536][INFO

And then:

][grid-nio-worker-tcp-comm-0-#24][TcpCommunicationSpi] Closing NIO session
because of unhandled exception [cls=class
o.a.i.i.util.nio.GridNioException, msg=Connection reset by peer]
These message persists after restart and even in the case of one node
running in separate zkRootPath. There are some environments with same
configuration which dont have similar behavior. What could it be?
