> Hi, We have a 4-node NiFi cluster. We use RPG to send flowfiles back to
> cluster. We faced the WEB UI slowness issue, so we found there are many S2S
> connection in CLOSE_WAIT state. After we restart the NiFi, the S2S
> connections are keep growing at each node, also, we can see there are many
> "socket time out exception" in log files.

> It may have some issue cause the NiFi does not close s2s connection.
