Maximum number of connections with HTTP Transport (Jetty)

Is there a limit to the number of connections that can be made to the ActiveMQ Broker over the HTTP (Jetty) transport? I seem to be hitting some default limit of 250 connections. If this is a limit, is there anyway to change it? Thanks, Rob -- View this message in context: http://old.nabble.com

Re: Exception in thread ActiveMQ Transport

Since I have had no luck in determining the cause of the exception, I am trying to at least handle it gracefully. What I am considering is applying the following patch to the InactivityMonitor in order to trigger a fail over on the transport... try {

Re: Exception in thread ActiveMQ Transport

Digging through org.apache.activemq.transport.InactivityMonitor I can't really see why this would occur and thus don't know how to prevent it. It looks like the WRITE_CHECK_TIMER was canceled somehow, and the CHECKER_COUNTER != 0... but why or how this occurred I do not know. Is there any help ou

Exception in thread ActiveMQ Transport

I received the following exception in a client application using 5.1.0 on both the client and broker: Exception in thread "ActiveMQ Transport: tcp://localhost/127.0.0.1:61606" java.lang.IllegalStateException: Timer already cancelled.\ at java.util.Timer.sched(Timer.java:354)\ at java.util.Timer.s

Re: ActiveMQ 4.1.1 server freezes

We identified what was causing the problem. One of our consumers had an uncaught exception that was occasionally thrown in the MessageListener thread. By simply preventing this exception we no longer see the broker lock ups. Is this expected consumer behavior? It seems that the broker/server shou

ActiveMQ 4.1.1 server freezes

I have been using ActiveMQ 4.1.1 for awhile in a production product and recently we have been seeing occasional lock-ups/freezes that go away when we restart ActiveMQ. From our clients or from the ActiveMQ log we cannot see that there is a problem, we just stop seeing message throughput . I'm at

Queue eviction policy

I dug through the website and the mailing list and am still a bit confused... Is there a way to set a maximum size (either by message count or memory size) on a specific Queue? Is there a way to specify an eviction policy, in the way you can for slow consumers, for a specific Queue? What I am t

I realized after I sent my original message that I didn't specify what type of clustering I was referring to. I think I understand how the routing rules would work in a master/slave setup but I'm still a little foggy on how they would function in a store and forward network of brokers. My goal in

EIPs in the ActiveMQ broker and clustering

I've been reading through the Camel documentation and about its incorporation in ActiveMQ 5.x at http://activemq.apache.org/enterprise-integration-patterns.html. I think the combination is going to be very useful to me and am just brainstorming about how I am going to apply both ActiveMQ and Camel

Another fly in the ointment is how should the Advisory destinations be permissioned for the client group? -- View this message in context: http://www.nabble.com/Authorization-Security-Question-tf4354381s2354.html#a12407602 Sent from the ActiveMQ - User mailing list archive at Nabble.com.

Authorization/Security Question

I'm having trouble getting my head around some of ActiveMQs authorization settings. I have a relatively specific use case I'm trying to meet, but can't quite figure out what the appropriate permission settings are. The read and write permissions I understand. The admin and temporary destination pe
