Subject Re: Disconnect client on AMQ restart
Date Fri, 20 Jan 2017 13:42:55 GMT
Can you please give more details about what you're seeing and how you are
determining that "The previous connection is not disconnected?"  Are you
saying that at the TCP layer a socket remains connected to a process that
is now dead?  Or do you mean something else by that statement?  And no
matter what you meant, can you please post whatever logs or command-line
output you're basing your conclusions on?

Hello,

I am using log4j2 JMSAppender to send logs to AMQ.
When I restart either the client application or AMQ I see:

JMSAppender connects as a new client connection.
The previous connection is not disconnected.

How can I make it so either the client connection is reused, or the
previous client connection is disconnected?

techonologies:
AMQ 5.14.0
log4j2

Thank you for your time.
