Hi. Maybe ActiveMQ is timing out the connection between BlazeDS and the ActiveMQ server which is then causing the JMS consumer on the BlazeDS side to be removed?
I looked at the ActiveMQ docs quickly and it did look like they have a connection timeout for the tcp connection to the ActiveMQ server. I'd look at the ActiveMQ docs and see if you can extend the connection timeout and maybe that will fix the problem. -Alex --- In flexcoders@yahoogroups.com, Christophe Herreman <li...@...> wrote: > > Hi, > > We are experiencing disconnects on our Tomcat/BlazeDS/ActiveMQ stack. > Although our BlazeDS StreamingAMFChannel is configured with the default > idle-timeout-minutes of 0, it seems to timeout after about 30 minutes of > idle time (see log).
