> Here is test reproducing issue
> https://github.com/rossdanderson/IgniteDeadlock.
> When I run this test observe this sequence:
> - server starts
> - client starts
> - server sends 2000 messages to client, on client node communication
> backpressure pauses reads
> - server gets write timeout and closes socket
> - for some reason client does not detect that existing connection was broken
> and thinks that connection is still established (most probably because reads
> are paused and node does not try to access connection)
> - when server tries to re-connec, client sees that connection already
> established and rejects connection, so server constantly tries to reconnect
> and does not exit from reconnect loop:
> {noformat}
