Why do I see a lot of connections on the message processors in CLOSE_WAIT state?

[akashtp]

I can see from the logs that there were EOFException thrown at the time of the issue.

2015-06-11 18:14:32,274 org:xyz env:prod NIOThread@1 ERROR HTTP.CLIENT - HTTPClient$Context$3.onException() : Message id: xyz.com_RouterProxy6195_682, SSLClientChannel[C:xx.xx.xx.xx:443 Remote host:.onExceptionRead exception: java.io.EOFException: eof unexpected

What are the probable causes for this exception?

As a workaround a rolling restart (one-at a time) of the MPs can be done. This would clear the open connections in CLOSE_WAIT state.

CLOSE_WAIT will go away after sometime. No need to restart.

The remote endpoint is closing connection, may be SSL handshake is not succeeding.
