Subject [jira] Commented: (AMQ-1746) ActiveMQ server does not release the connection on a reconnect
Date Thu, 05 Jun 2008 06:07:00 GMT


Hari commented on AMQ-1746:

I have been working on this for a while now.  I tried a bunch of things. 

1) i made changes to in the addconnection so when a new connection request
comes in and there is a oldcontext associated with the clientid then to explicitly close the
old connection by getting it from the oldcontext and closing it. this solves the problem of
having multiple connections on the server side to a client who has one connection from his

In a scenario where a client is disconnected for some reason(unpluggint he cable or the system
crashing) and if there is no reconnect at all, there is noway the server knows to close the
connection. server keeps sending to that connection. the outqueue on the socket increases
to close to 98000 and then the server does not serve the other connected clients as well.

I am using apacha client. On a connect it receives messages and on a regular shutdown
the connection is disconnected and everything shutsdown w.r.t that connection in the server
side. Now if there is network issue or when we disable and enable the network from the client
side , a reconnect request is sent with a new clientid and the connection is established.But
the old connection is still active which is evident from a netstat on the server machine.
The client side netstat shows only the latest connection which is on port 1870.
