Most changes to config are applied to existing connections. Changes to the set of profiles used
by a connection only apply to new connections. Since many message routing protocols use long
lived connections, some config changes will not effect existing connections. For example
replacing the router profile used by a virtual server will not apply to existing connections.
Thus all traffic on existing connections will still be routed through the previous router
instance and the stats for that traffic will be included with the previous router instance. To
apply the traffic to the new router instance, the existing connections will need to be closed
forcing the clients to create new connections.
