At work we currently have MQ 6.

How with MQ 6 can you prevent one application or one set of IP's from grabbing more than their fair share of connections?

Is Security Exit the only way?

Also in MQ 7 ... can you limit the number of connections from a given IP address to a SRVCON channel?

Maxconnections is 3000 but some misbehaving apps grab 1000+ connections which spoils it for everybody else.
