Re: How many connections does an AMQ client really need to the broker ?

You'll have to take stack traces/thread dumps of the consumers to see what they're doing, and why they aren't consuming. On Thu, Jul 25, 2013 at 12:21 AM, minglin wrote: > No one has some advice? > > > > -- > View this message in context: > http://activemq.2283324.n4.nabble.com/Some-of-active-c
