Subject Re: tcp retransmission with activemq 5.3.x
Date Mon, 28 Nov 2011 15:03:48 GMT

Have seen these as well in the past.
This should all come from your OS, not from ActiveMQ. Its tcp level retransmission of tcp
packets. Higher network layers should not even see these. 
Typically this happens on dodgy network connection, but AFAIK can also happen if your connection
crosses from a fast to a slower network. 

None of this should be caused by ActiveMQ from what I know.
